JVM _is_ different. JVM defines special fields for the line
numbers of the source code in the byte code. That's what the
OP was asking for. Some years ago I studies the JVM spec and
after this I knew why the de-compiled/disassembled byte code
had such a high quality and readability. There are tools for
removing these "comments" from the byte code.
JVM is also different in that it doesnt know the concept
of a pointer. This disadvantage is essential when comparing
.NET binaries and Java byte code.
