I actually had to change the way that worked. Seems like the Method[]
the Class.getMethods() is in a different order if you run in different
JVMs. Well at least that's what I noticed. So for now I'm sending down
a String the represents the method sig until I find a way to get an Int
to represent the method.
So how can we get 2 jvms to agree on the same ordinal number mapping??
Use the RMI hashing algorithm:
http://java.sun.com/products/jdk/1.2/docs/guide/rmi/spec/rmi- stubs.doc3.html
the string containing the remote method's name and descriptor would be the following:
myRemoteMethod(ILjava.lang.Object;Z)V
The hash value is assembled from the first two 32-bit values of the SHA-1 message digest. If the result of the message digest, the five 32-bit words H0 H1 H2 H3 H4, is in an array of five int values named sha, the hash value would be computed as follows:
long hash = ((sha[0] >>> 24) & 0xFF) |
((sha[0] >>> 16) & 0xFF) << 8 |
((sha[0] >>> 8) & 0xFF) << 16 |
((sha[0] >>> 0) & 0xFF) << 24 |
((sha[1] >>> 24) & 0xFF) << 32 |
((sha[1] >>> 16) & 0xFF) << 40 |
((sha[1] >>> 8) & 0xFF) << 48 |
((sha[1] >>> 0) & 0xFF) << 56;
