Bug 52218 – Java applications fail to start after upgrading to Gnome2.6 with accessibility enabled

• Status: RESOLVED NEEDINFO
• Product: Gentoo Linux

[Description Jose Gonzalez Gomez 2004-05-27 15:16:41 UTC]

After upgrading to Gnome 2.6 with the accessibility USE flag enabled, graphical Java applications refused to start, complaining about Java Assistive Technology problems.

Reproducible: Always
Steps to Reproduce:
1. Upgrade to Gnome 2.6, with USE including accessibility
2. Start any graphical Java application
3. Search for cover so the bang doesn't catch you unprotected

Actual Results:  
All the graphical Java applications refused to start, complaining about problems
with the Java Assistive Technology

Here is the output from JXplorer:

jgonzalez@bit tools $ java-config -L
[sun-jdk-1.4.2.04] "Sun JDK 1.4.2.04" (/etc/env.d/java/20sun-jdk-1.4.2.04) *
[sun-j2sdk-1.4.1] "Sun JDK 1.4.1" (/etc/env.d/java/20sun-j2sdk-1.4.1)
[sun-jdk-1.5.0_beta1] "Sun JDK 1.5.0_beta1" (/etc/env.d/java/20sun-jdk-1.5.0_beta1)

WORKAROUND:

First I tried to reemerge app-accessibility/java-access-bridge-1.3.1, with no
success (I had errors while compiling), so I emerged 
app-accessibility/java-access-bridge-1.4.2. This version of the package emerged
successfully, but Java applications still refused to start. Then I installed
java-sdk-1.5.0-beta1. This solved the problem.

Maybe the dependencies should be fixed, so <sun-jdk-1.4.99 cannot be used with
Gnome 2.6

[Comment 1 Leonardo Boshell (RETIRED) 2004-05-30 14:35:34 UTC]

I really doubt the dependency should be >=sun-jdk-1.4.99 since, as far as I know, the java-access-bridge package was developed using the Sun JDK v1.4.

Anyhow, I don't use the Sun JDK, and I can't really test this. I'm going to have to ask that someone from the Java team take a look at this.

By the way, what were the errors with java-access-bridge-1.3.1?

[Comment 2 Jose Gonzalez Gomez 2004-06-03 10:48:41 UTC]

I have tried to reproduce the error, but right now java-access-bridge-1.3.1 is emerging correctly in my system. Anyway, I have reemerged gnome without accessibility support since I got the error.

No more useful info here... assuming it's not reproducible. Please re-open if the problem still exists and there's new information.
