Description

Adding JDWP & JVMTI support
JDWP & JVMTI are standards introduced by sun to uniform the way JVM[s] are debugged/queried. They are not mandatory nor do they form requirements to comply with the JVM standard
Java Debug Wire Protocol is an interface specification to debug/query the JVM status. It defines the format of information and requests transferred between the process being debugged and the debugger front end. JVMTI s a low-level native interface ( based on JNI) that defines the services a Java virtual machine provides for tools such as debuggers and profilers(which they are implemented as agents).

helpful commands

-Running the rvm in server mode waiting for a consuming IDE
./rvm -Xms256m -Xmx1024m -X:processors=1 -X:runjdwp:transport=dt_socket,address=localhost:1234,server=y,suspend=n -X:use:rvm:socketimpl=y

Spying on the protocol
=================
In the eclipse 3.3RC4 installation run the following (older versions fail throwing exception)
java -cp plugins/org.eclipse.jdt.debug_3.3.0.v20070530a/jdimodel.jar:plugins/org.eclipse.osgi_3.3.0.v20070530.jar:plugins/com.ibm.icu_3.6.1.v20070417.jar org/eclipse/jdi/internal/spy/TcpipSpy 6900 localhost 1234

Testing with RvmSocket Implementation
===============================
add the following

  • X:use:rvm:socketimpl=y

IDE
===
You can attach a running rvm instance using eclipse->run->debg-
you may want to increase debugger time out in eclipse->preferences->java->OpenDebugDialog->Remotejava application

Running the debugger thread
=======================
kill -sigquit `ps aux | grep JikesRVM | tr -s [:blank:] | cut -d' ' -f 2 | tr "\n" ' '|cut -d ' ' -f1`
