Has Eclipse (outside of Tomcat) been configured to emit .class files in
a certain format? I'm guessing this hasn't been done for 'ant', so maybe
they need to match each other.
that was one of my guesses, but apart from the compliance level i dont
know of any-
This happens as well under tomcat 5.5.
Changing the ANT build to use the same JDT compiler as eclipse did not
change the problem.
Using javap I checked both compiled versions of the classes and they do
have the same major version.
Really? Hmm. Could you double-check that and post what you get?
It's possible that there's a bug in the compiler that can't read some
particular thing in the class file.
please find javap - verbose output attached. major and minor versions
are the same.
there are differences though. Eclipse sems to include a SourceFile
reference plus Linenumber and LocalVariable Tables.
I wouldn't know how to trigger that in ant though..
