[cme-dev] JSR45 support is in; NEED NEW CLASSPATH VARIABLE

[Harold Ossher <ossher@xxxxxxxxxx>]

I have just checked in support for JSR45, which causes the debugger to show
the proper source when debugging composed Java programs. It is currently
enabled for tests in citcat.jikesbt. I plan to work on enabling it for ccc
composition and its related tests shortly.

The new support uses Sun's tools.jar, which is part of the Java JDK but not
usually on the classpath. You therefore need to add a new classpath
variable, JRE_TOOLS, defined to be the "lib/tools.jar" file within the JDK
you are using (Window -> Preferences -> Java -> Build Path -> Classpath
Variables).

Many thanks to Jeff Palm who wrote this support - it should make working
with composed programs MUCH easier.
