JVM crashes when adding more than 2 methods to java.lang.Object

First of all I hope it is appropriate to ask this kind of question in
this list, otherwise what would be the correct forum?
Here is my problem: I'm adding public, non-native methods to the
Object class through instrumentation, and it seems that adding more
than 2 such methods causes the JVM to crash. I get different kinds of
crashes depending on the number of methods I add. With 3 and 4 methods
I get a SIGSEGV; with more methods I get an NPE during VM
initialization (in String.charAt). For testing purposes, all added
methods take no arguments and return void, and have an empty body
(only the RETURN bytecode).
Is that expected behavior? Is there something I can do about it?
