One thing you should keep in mind, on the general issue of debugging
information, is that there is a Java Specification Request (JSR-045) currently
under way which will standardize mechanisms for storing debugging information
for non-Java languages that are translated into Java source code -- JSPs being
an obvious example -- into the class files themselves.  Jasper in the 4.x tree
is going to track the results of that effort when they come out.

You can get more information about JSR-045 at the Java Community Process web
site <>.
