ami tabak commented on JASSIST-177:
-----------------------------------
I noticed a mismatch between the ojdbc6.jar manifest and the actual major number of the
problematic class in the example. The class major number is 50 but the manifest states jar
was build using java 1.5 which as far as I understand should result in major number 49.
I see that javassist bases its decision whether to support the java6 based on the major
number. Could it be that Oracle had a bug on their side in one of the compilers which
wrote the wrong major number to the class file ? Is there any other way to verify class
file structure?
