[antlr-interest] Antlr grammar to parse Java classfile?

First of all, I don't know about the existence of such a (n ANTLR) grammar.
I know pretty much the java .class file format. As it is straighforward, I
have built a package that reads and writes this file format.
Based on that experience, I think the main problem of building such a
grammar would be to apply a certain rule a specific number of times (for
instance you read the number of methods the class file holds and based on
this number, you iterate to read every method). This is the main
characteristic of the .class format (as well as of many binary file format).
I know that predicates are one of the features ANTLR has. I think this could
be the only salvation... However, if you manage to find an existing grammar,
please let me know.
PS.: You may find the exact description of the .class format in the Java
Virtual Machine Specification.
