Re: [cross-project-issues-dev] Intalling with java 6 cannot recover

Yes, -clean does still do something.  If it actually fixes anything is another topic.

It clears the osgi cache of installed bundles which then forces p2 to re-install everything.  You can clearly see it doing something in this scenario.  After you install CDT on top of RC3 and have a look at the osgi> console with the 'ss' or 'lb' command you will see a listing of the bundles where the cdt bundles are the last bundles in the list (with the highest bundle IDs) because they wre the last ones installed.  Then if you restart with -clean and look at the bundle listing again you will see that the bundles got re-installed in alphabetical order (since that is how p2 sorts them in the bundles.info file).

Sadly I did launch with –clean and it didn’t help.
 
Since it should be fixed in M7, we’ll try to reproduce on another machine to make sure it is not my environment.

This sounds like https://bugs.eclipse.org/bugs/show_bug.cgi?id=432485

But that should have been fixed in M7.  I am curious if launching with -clean fixes the issue.  I would start with a bug against Equinox Framework if it is what I suspect (somehow the framework is not forcing a refresh of the system bundle to update its capabilities to include the Java 7 execution environment).

Hi,

I'm testing installing CDT on RC3.  CDT requires Java 7.
My system switched to java 6 under my feet, so I ended up installing CDT using java 6.
The install worked but when running, most CDT plugins didn't start and I got some errors due to java 6.
I then switched back to java 7 and ran the already installed version.
Surprisingly, things still failed but no errors reported.

So, it looks like installing plugins that require a newer java than what is running is non-recoverable.

Is this a bug I should report? If so, to what component?

Thanks

Marc
