Actually, I've reverse engineered JVM code and 80x86 code (for mostly-
legitimate reasons), and JVM code is considerably easier. This is mainly
because the structure of each class is exposed in the classfile format,
and also because you can easily replace classes individually.
OTOH, the difference is simply in the degree of obscurity, not in whether
reverse engineering is possible.
