Hi Abel,
Your assumption is right for all methods except "Static methods". Static methods do not keep
a reference to the "this" object in its Local Variables table. Positions 0 to N-1 would point
to the parameter's list for static methods and 1 to N for all others.

Hi BCEL users, thanks for all the help you guys have provided!

Ok, one last question:

I'm trying to get the index of the parameters in a specific method call.
there any easy way to do this?

What I'm currently doing is I've parsed an object using ClassParser into
JavaClass.  From there, I can get the Method object of a particular
in that class.  I then parse the method name to get the names of the
parameters in the method's parameter list.  I then get the
LocalVariableTable from the Method object, going through all the
until I find the ones whose names match the variable names in the method
parameter list.  And from there, I can get the index.  However, I just
across a case where the method parameter list names do not match the
in the LocalVariable table.  So, I guess my question is, what would be
right way to do this?  Can I assume that position 0 in the
LocalVariableTable points to this, and 1 to N (N being the number of
parameters in the method) points to LocalVariable objects of the
