I am not able to reproduce it

no sorry .. I am able to reproduce it 100% : 
- just expand Databases node and IDE will crash (5 from 5 times)

More evaluation on Marian's computer - happens with JDK 7u4, but does not happen with JDK 7u3.

Jesse, which part of our interaction with the gnome keyring library is causing it? Any clue why it starts crashing only with 7u4?

... and more evaluation :
- running 64b system & 32b JDK seems to be key combination :

I am running Ubuntu 11.10 x64 , Gnome :
.... 7u4 b20/b19 , 6u32 b05 - all 32b -> crash
.... 7u4 b20/b19 , 6u32 b05 - all 64b -> works without problem

Not true. Jirka reproduced on his 64bit Ubuntu with 7u3 32bit + 7.1.1 (the previous JDK bundle).

As Marian notes above, it is 32bit Java on 64bit Ubuntu which is the key.

Release Note for NB 7.1.2 :
IDE crashes when user runs any operation using keyring when running 32b JDK on 64b Ubuntu. Workaround : use 64b JDK on 64b Ubuntu.

Will try if JNA 3.4 will help (issue 211403).

I use a 32-bit JDK on 64-bit Ubuntu every day without problems.

Using "Linux jglick-t400 3.0.0-17-generic #30-Ubuntu SMP Thu Mar 8 20:45:39 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux", I downloaded jdk-7u4-fcs-bin-b20-linux-i586-12_apr_2012.tar.gz and tried running 20120419-72fa32370df8 and expanding the Databases node - no crash.

I can also reproduce it 100%. Seems like a duplicate of my bug #209226.

netbeans-7.1.2-ml-javase-linux.sh worked fine too.

Maybe someone who can reproduce this (at least occasionally) can help debug it; I cannot do anything based on the crash report.

Without an evaluation of what is wrong, I do not think we can say that the problem is in fact JDK-specific. Nor is a release note in order for a P1 bug unless we know why it happens and that we cannot prevent it, especially when it is suggested that there is no recent regression in NetBeans itself.

It happens to me on Ubuntu 11.10 32b & 32b JDK 7u4 with trunk builds and latest 7.1.2 (I switched from 64b Ubuntu because I thought it will help but it didn't)

BTW, for me it also happens with JDK 6 Update 32. I installed 7.1.2 SE & 6_32 bundle, installed Java Web Applications plugin, restarted IDE and now every attempt to open JSPExamples application [1] crashes the IDE.

I can't reproduce it in latest trunk (perhaps #211401 fixed it?), here's log from build 201204170400 on 32b OS


Product Version: NetBeans IDE Dev (Build 201204170400)
Java: 1.7.0_04; Java HotSpot(TM) Client VM 23.0-b21
System: Linux version 3.0.0-17-generic-pae running on i386; UTF-8; en_US (nb)

I also confirm that the latest dev build does neither crash when saving password to the keyring nor when opening web application!

Product Version: NetBeans IDE Dev (Build 201204220400)

User directory: /home/cesilko/.netbeans/dev
Cache directory: /home/cesilko/.cache/netbeans/dev

I can confirm it is not reproducible on latest Dev build IDE (Product Version = NetBeans IDE Dev (Build 201204230400) (#6894fc2ff9d3)).

The older builds (e.g. Product Version = NetBeans IDE Dev (Build 201204190400) (#83b5156ac3f7)) crashes  every time when accessing Keyring on my machine. I think the newer JNA 3.4 solved this problem and we can close as fixed. Am I wrong?

Perhaps. No one knows what the problem was, and what particular change in JNA might have corrected it, or whether the problem disappeared (for now?) for some other reason.

Mark as fixed by #rev/836f5c2762c5. If the problem appears again, please reopen it with all available details. Thanks

Product Version: NetBeans IDE 7.1.2 (Build 201204101705)
Java: 1.7.0_04; Java HotSpot(TM) Client VM 23.0-b21
System: Linux version 2.6.38-8-generic running on i386; UTF-8; en_US (nb)

1. downloaded jdk-7u4-nb-7_1_2-linux-ml.sh from http://smetiste.cz.oracle.com/builds/netbeans/7.1.2/bundles/jdk-7u4-nb-7_1_2/2012-04-17_21-48-09/
2. installed jdk-7u4-nb-7_1_2-linux-ml.sh
3. opened some J2SE projects
4. selected Services view
5. expanded Databases node

-> everything seems fine

Tested on Ubuntu 11.04 32b (in VirtualBox that runs on Linux Ubuntu 11.10 32b), downloaded from beetle.cz.oracle.com (Linux_Ubuntu_Machine.vdi.zip).

BTW the most direct way to check a given OS/JDK/NB combination is

$ ant -f keyring.impl -Dnbjdk.home=... -Dpermit.jdk7.builds=true -Dtest.includes=org/netbeans/modules/keyring/gnome/GnomeProviderTest.java test-single

(This will check functionality more thoroughly than just expanding Databases, which only happens to use the keyring at all due to a bug in the current database support, and merely reads a certain key without writing anything.) If all is well you should see

Testsuite: org.netbeans.modules.keyring.gnome.GnomeProviderTest
Tests run: 1, Failures: 0, Errors: 0, Time elapsed: 4.058 sec

If the test fails, or passes but prints "org.netbeans.modules.keyring.gnome.GnomeProvider@3eda834c disabled on Linux, skipping", then the provider is broken.
