Compiling project using apache mina fails

Fri Jun 5 14:38:00 GMT 2009

Hi,
I am trying to compile a project using the apache mina library to 
native code using gcj. I succeeded building the native library but the 
program fails with an exception while trying to access 
VMThreadMXBeanImpl. getThreadInfoForId():
java.lang.UnsupportedOperationException: 
gnu::java::lang::management::VMThreadMXBeanImpl::getThreadInfoForId 
(jlong, jint) not implemented

Is there any workaround for the missing function (alternative 
implementation)?
I am using gcj version 4.3.3 on Mac OS X.
Thank you very much for any help!
