Description

Hi,

I’m not able to open the "EPackage Registry" view: I get the following error:

I got almost the same exception, but with "UnsupportedClassVersionError", because I had compiled with Java 6 and run with Java 5.

Created attachment 178747 patch

Here is a patch that catches the exceptions and logs them, so that one single EPackage failing to load doesn't crash the whole view.

I committed this on trunk (revision 3024). Should this be applied to branch 0.8 as well?

Hi,

I think that this patch should be applied to branch 0.8.

Note that, technically, PMC approval is not required to fix issues in a service release (although, depending on the nature of the issue/fix, it's not necessarily a bad idea)...
