I think the fix from the latest one should make it work more widely in
3.2versions.
3.1, I don't know. Certainly some parts will not run, but perhaps the editor
and wizards will, but probably not well. 3.2 final will be out in June. Our
issues with M6 over M5 were not due to Eclipse APIs, but due
. The
nullPointerException will only happen when there is no package declared in
drl file. Maybe it is because the rules folder(drl and dsl files) already
defined in configuration-file .classpath?
thanks

no it should work against any interface you can compile java code against.
It just looks for any methods that take no parameters, and return something
- interfaces and abstract is fine, as are multiple inherited interfaces.
(can't remember what I fixed for RC2 specifically, though).
Providing
to wrapping assert with code to check
for equality.

OK I thought this may cause an issue.
As Yuesong said, it was handy to be able to spread conditions across lines
(sentences in DSLs) as it made it more readable. Now when we do that, it
won't work.
So what do we do? Allow the identity cross product?
In simple cases, yes it does make things
That particular error looks like JCI itself is missing, or you have an old
one from RC1 possibly hanging around.

Hi guys,
looks like RC2 has included a new class PackageBuilderConfiguration. With
RC1 everything worked as expected when deployed
the correct stuff was
getting built into the ear and the runtime classpaths were updated to the
new RC2 jar file names. I'll double check it though.
