[jdt-core-dev] Some bytecode (class files) are different between batch c

[Wei Chen <joyuan@xxxxxxxxx>]

Hi all,

We recently noticed that for some of our classes, the bytecode class
files are different between the commandline batch compiler (invoked
via ant) and eclipse. It doesn't happen to all of our classes, but
many of them are different. Ideally we would like to see the class
binaries to be the same from development (eclipse) to production
(ant).

We have ruled out most of the compiler settings (e.g. java level,
debug info, and etc). And clueless at this time. Can someone shed some
light?

Details:
Development is using MyEclipse 10.6 (Eclipse indigo based)
Production build is performed by Ant 1.8.2 which uses
org.eclipse.jdt.core-3.7.3.v20120119-1537.jar that copied our of the
MyEclipse 10.6 installation.
java source/target level: 1.6

Thank you very much.
Wei
