How to become a volunteer for bug fixing?

[wh...@sybase.com]

Hi there,

I just submitted a critical bug (#34959) for commons-modeler. Here's the 
description:

Bug ID: 34959
Summary: Overloaded operations throw "wrong number of parameters" 
exception

Description:
If a model MBean has an overloaded operation (an operation with two or 
more signatures), 
only one of them can be successfully invoked at runtime. Invoking others 
will throw 
"Wrong number of parameters" exception.

Through initial investigation, I have found out the cause of the problem:

Class org.apache.commons.modeler.BaseModelMBean internally stores and 
caches
operations in a hashmap. The key to the hashmap is the operation name. 
Therefore,
if an operation has multiple signatures, only one of them (the first one 
loaded) is stored
in the hashmap. Invoking the same method with a different signature will 
cause
"wrong number of parameters" exception.

I have been using Apache commons libraries for years and would like to 
contribute something back to the 
community. Can someone tell me how to become a volunteer for bug fixing?

Thanks,
