ClassNotFoundException under jvm 1.6
------------------------------------

         Key: HADOOP-325
         URL: http://issues.apache.org/jira/browse/HADOOP-325
     Project: Hadoop
        Type: Bug

  Components: ipc  
    Versions: 0.3.2    
    Reporter: Owen O'Malley
 Assigned to: Owen O'Malley 
     Fix For: 0.4.0


We have been having problems with classes that are returned by RPC methods not being loaded/initialized correctly. The work around has been to put in the servers, code of the form:

static { new FooBar(); }  // to resolve the ClassNotFoundException for class FooBar.

When I tried running under java 1.6, that stopped working because one of the classes had to be instantiated from a package that didn't have visibility to create an instance. So I tracked the problem down to how the classes were being loaded via reflection.
