Interesting... jsr14 is used as walk around for Java 5 compiler,
currently all Harmony VM (including IBM VME) haven't fully support 5.0
class format, so we need this option to compile the source codes with
5.0 syntax to 1.4 compatible binary code, it should not be set if 1.4
compiler is used. Seems a bug of build script? Haven't look inside what
actually happened, but maybe you have interest to: 1. either find and
remove the setting about jsr14 and remove it(I'm not sure where it is
for DRLVM, but for classlib, it is in
enhanced/classlib/trunk/make/properties.xml) 2. or try a Java 5
compiler(I prefer this one :)). Good luck!
