JDLabAgent is a dynamic link library which is loaded into the Java Virtual Machine via Java Virtual Machine Debug Interface (JVMDI). The JDLabAgent can be parameterized via config files and logs JVM events (e.g. breakpoints, exceptions).
This is a dynamic slicing tool for Java programs. The tool modifies the Kaffe virtual machine to collect the execution trace, and compress the trace on-the-fly. Please proceed to the tool's website http://jslice.sourceforge.net/ for download.
