Description Andrew Overholt 2009-05-29 18:10:18 UTC

I'm pretty sure we just follow upstream's MANIFEST.MF/build.properties files so I thought we were good here.  Apparently we're not, though.  See:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=278276

As we're re-doing how we build for Fedora 12, let's re-examine this to avoid odd corner-cases.

Comment 1 Bug Zapper 2009-06-09 16:49:04 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

Comment 4 Fedora Admin XMLRPC Client 2010-09-10 17:00:52 UTC

This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.

Comment 5 Alexander Kurtakov 2011-02-18 11:31:27 UTC

Is this still true in Fedora 14?

Comment 6 Andrew Overholt 2011-02-18 14:04:08 UTC

I unzipped the JARs bundled into ant.ui's lib directory.  All class files are bytecode version 46.0 (Java 1.2) so I think we're good to go here.

I'm going to rename this bug to reflect what needs to happen in an ideal world.  We would like a script that goes through an upstream Eclipse build (see download.eclipse.org/eclipse/downloads) and compares with the JARs in our eclipse-{swt,jdt,rcp,platform,pde} RPMs.  All bytecode levels should match.  Just running `file` on a .class file will show its bytecode level.

Comment 7 Alexander Kurtakov 2011-02-18 14:19:44 UTC

Matching bytecode version makes sense for all bundles part of eclipse makes sense but e.g. if we ship with newer lucene that builds newer bytecode version by default we might not even be able to build to the old one.

Comment 8 Andrew Overholt 2011-02-18 14:25:56 UTC

I didn't say there weren't edge cases :)

Comment 12 Alexander Kurtakov 2012-05-10 20:50:02 UTC

CLosing the bug as we would never manage to have the exactly same jars hence such script would give us no benefit.
