Insistence on CurrentJDK causing problems

[whaleyr]

I'm running OS X 10.8. I need to use JDK7 for my main codebase so I have the Oracle JDK7 distro installed. I switched my /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK alias to point to JDK7. This has caused problems with some apps that still need JDK6 (like Gephi) so I have /System/Library/Frameworks/JavaVM.framework/Versions/1.6 as an alias to JDK6.

I see that Gephi insists on JDK6. I modified gephi.app/Contents/Resources/gephi/etc/gephi.conf and updated the jdkhome pref to point to the JDK6 path. However, when I try to start gephi I get the following error message.

Code: Select all

Loading native libraries
Issue #452: Can't locate the default Libraries folder to load theJAWT library. This library is needed as a dependency of jogl_awt and isnormally installed in the JDK. To fix that please make sure to have the /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK path points to the current Java installation.

I see that it says it's using the JDK6 VM but it's still not working. As an experiment, I switched the CurrentJDK alias back to the JDK6 path and the app starts just fine.

My question: what am I doing wrong here? Am I misunderstanding the use of the jdkhome pref? Should I be doing this differently? How can I keep CurrentJDK pointing to JDK7 and still get gephi working with JDK6?

[eduramiba]

Hi,
It seems that in MacOS it is necessary to load jawt before jogl 1.1, and in our code, current jdk is checked for existence before java.home (See this file https://github.com/gephi/gephi/blob/mas ... .java#L154).

I am not sure why not use java.home first directly. I think we could try to locate jawt in both places.
Meanwhile, you can try to copy jdk6 jawt to jdk7 while we fix this.
