I'm not surprised by this difference and would argue that the process by which in the past you managed to get the same jar is coincidence / luck, or some wonky things that the BIRT team did :)
Several reasons come to mind as to why there is a difference: - the Eclipse build process condition the jar (pack200 then unpack200 it) which rearranges the bytecode - you may be using a different version of the compiler than the one that has been used during the Eclipse build HTH Pascal On 2012-03-28, at 4:13 PM, Hardin, John wrote: > The OSGI jar file included with the 3.7.2 version of the BIRT runtime is > org.eclipse.osgi_3.7.2.v20120110-1415.jar. > > When I extract the v20120110-1415 version of the equinox framework from here > (http://git.eclipse.org/c/equinox/rt.equinox.framework.git/tag/?id=v20120110-1415), > and manually build theorg.eclipse.osgi “bundle” with Eclipse, I get jar > contents that are almost completely different than the jar included with BIRT. > > To compare the jars, I first expand them, run md5sum on all of the > constituent files, and compare the results.
