    BTrace is a safe, dynamic tracing tool for the Java platform. BTrace can be used to dynamically trace a running Java program (similar to DTrace for OpenSolaris applications and OS). BTrace dynamically instruments the classes of the target application to inject tracing code ("bytecode tracing"). Tracing code is expressed in Java programming language. There is also integration with DTrace for the OpenSolaris platform.

Handling exit in agent mode
Maybe I'm approaching this the wrong way, but I want to gather complete statistics about the behavior of my program. So I'm using the agent to start tracing at the beginning of the program's run. The . . .

Is it possible that the 1.2 release in the maven repository is somehow different from the 1.2 release on the download page? I just spent some time trying to track down a problem with using the javaage . . .
