Hi all,

I tried to start MyEclipseIDE with the newest JDK 6 (1.6.07) and behaves really strange: A lot of plugins fail to start with weird exceptions:

I start MyEclipseIDE with following arguments:

“C:\Programme\MyEclipse 6.5\eclipse\eclipse.exe” –vm “C:\Programme\Java\C:\Programme\Java\jdk1.6.0_07\bin\javaw.exe”

Any ideas what is possibly wrong here?

With the previous version of JDK 6 (1.6.06) it was running perfectly.

Thanks!

Lorenzo,
MyEclipse is not certified to run with JDK 1.6 just yet. Maybe the new 1.6 build is causing some compatibility issues.

Also, the “java.lang.UnsupportedClassVersionError: com/genuitec/eclipse/examples/core/RepositoryConfigurator (Unsupported major.minor version 49.0) ” error suggests that there is a compatibility issue as well.

Are you sure the plugins that your working with are compatible with this build of JDK 1.6?

Hi Nipun,

I did not know that MyEclipse is not certified with jdk 1.6. I tried 1.6, because it is much faster than 1.5 (at least during startup). Well, if it is not certified i have to wait until it is. Do you have an idea when this will happen?

Thanks for your help!

We don’t have an ETA for this feature. I’ll keep you posted.
