SortedList does not at all (ArrayIndexOutOfBoundsException)
What I am doing wrong - because I can't believe that these basic operations do not work
ObservableList < String > x is FXCollections. < String > observableArrayList(); | |
SortedList < String > s = x.sorted (String.CASE_INSENSITIVE_ORDER); | |
x.addAll ("A", "B"); System.out.println (s) |
Instead of 'A', 'B', I get an exception:
java.lang.ArrayIndexOutOfBoundsException
at java.lang.System.arraycopy (Native Method)
at javafx.collections.transformation.SortedList.ensureSize(SortedList.java:282)
at javafx.collections.transformation.SortedList.setAllToMapping(SortedList.java:345)
at javafx.collections.transformation.SortedList.addRemove(SortedList.java:388)
at javafx.collections.transformation.SortedList.sourceChanged(SortedList.java:105)
to javafx.collections.transformation.TransformationList$ 1.onChanged(TransformationList.java:109)
at javafx.collections.WeakListChangeListener.onChanged(WeakListChangeListener.java:87)
to com.sun.javafx.collections.ListListenerHelper$ SingleChange.fireValueChangedEvent (ListListenerHelper.java:158)

at javafx.collections.ModifiableObservableListBase.addAll(ModifiableObservableListBase.java:102)
at javafx.collections.ObservableListBase.addAll(ObservableListBase.java:245)
[...]
That seems quite obvious, because setAllToMapping is to change the size of the new value, and then by calling ensureSize with the new size
size =;
ensureSize (size);
but the current size of the copies ensureSize to new table
Replacement of element < E > [] = new item [size * 3/2 + 1];
System.arraycopy (sorting, replacement, 0, 0, me.) Size);
Sort = replace (element < E > []);
I have a strong feeling that ensureSize must be called before changing the internal size. If anything, so the size can be set to zero before calling ensureSize to avoid any copy for this method.
Is there something that I have wrong here or is it just a big bug? And how the sorted list can not work at all in this case - I can't work with any combination of adds/game/replace/whatever.
And Yes, while he was working under b111, I see the same error that you stated under b114.
I have tabled a JIRA for this to https://javafx-jira.kenai.com/browse/RT-34088 as this is clearly a bug.

Skype notification sounds does not at all RESOLVED
On Win 7, I installed Skype 6.21 but notification sounds worked... When I checked the settings and tried to play all the sounds, it does not makes all the sounds as well.
I decided to uninstall it and install Skype 6.22, but it has the same problem... I checked google if there are similar problems, but I found only old Skype 5 forums and so on and no one has helped me solve my problem. No idea what to do?
RESOLVED: the reason why it didn't work was the scene of singing! For all those who have the same problem, the solution here:
Tools > Options > Audio settings, look for the "Ringtone" section, if said option 'speakers use selected', to 'double headphones and speakers.
In Skype, open Tools-> Options-> sounds. The text on the button says "Mute all sounds"? Be aware that if the text is "Activate all sounds", then all sounds are actually set on mute.
In addition, open Tools-> Options-> Audio settings. Which device is selected for "Ringing"?

CCleaner is very useful to get rid of temporary files, you can get it here: http://www.piriform.com/ccleaner you can use it to clean your temporary files, but DO NOT use registry cleaning works, registry cleaning is mainly a useless effort that can cause more harm than good.

Thanks for posting your question in the Microsoft answers Forums.
Just so I'm clear, updated you the graphics cards in Device Manager? You have access to a Windows XP installation disc. If so, follow the steps in this document to make a scan of the SFC. This analysis will attempt to repair or replace any missing or corrupted system files.

Computer is very slow and IE does not work all the time.
I bought a computer from my old employeer. He is doing all sorts of things, or should I say not to do all sorts of things. It is very slow and IE does not work all the time. They have questions arise and ask if the administrator oks things and other things like that. It came with any disks. I would like to wipe, clean and load a new disc, but I don't know where to find the disc or if I can do it. Can someone please?
Hello
Proceed as follows to contribute to these two questions. You can probably buy the disks of Vista machine to system or get
the former employer to do it for you if necessary.Try these and it can also be a good idea to update your main drivers later. The General corruption can also play a
role in this issue. And even the TCP/IP stack might need to be refreshed.What antivirus/antispyware/security products do you have on the machine? Be one you ALREADY had on this
machine, including those you have uninstalled (they leave leftovers behind which can cause strange problems).If no joy there's something blocking perhaps.
Start - All Programs - Accessories - System Tools - IE with no Addons - what works best?
IE - Tools - Internet Options - Advanced - tab click on restore, and then click Reset - apply / OK
IE - Tools - Internet Options - Security tab - click on reset all default areas - apply / OK
Close and restart IE or IE with no addons
not better?
IE - tools - manage Addons (for sure disable SSV2 if it is there, it is no longer necessary but Java always install
"(and it causes problems - you never update Java to go back in and turn it off again)." Search for other possible problems.Windows Defender - tools - software explore - look for problems with programs that do not look right. Permit
are usually OK and "unauthorized" are not always bad. If in doubt about a program to ask about it here.Could be that a BHO - BHOremover - free - standalone program, needs no installation, download and run - not all
are bad, but some can cause your question (toolbars are BHO).

For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
Control Panel - Device Manager - Display Adapter - note the brand and complete model of your
video card - double - tab of the driver - write version information. Now click on UPdate Driver (this
cannot do anything as MS is far behind the certification of drivers) - then do a right click - Uninstall - REBOOT
This will refresh the driver stack.Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party with their
own the software and drivers and all other main drivers that you have.Now go to the site of the manufacturer of system (Dell, HP, Toshiba as examples) (restoration) and then of the manufacturer of the device
(Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for the BIOS, Chipset and software)
updates on the site of the manufacturer of the system here.)Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after each installation.
Repeat to the manufacturers - BTW on device at the DO NOT RUN THEIR SCANNER - manually check by model.
Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.
