Bytecode generation, Source code mappings, JCov, Future (Patch)

[Jonathan Gibbons]

Hi Serviceability folk,

The Subject line is from a thread on the compiler-dev list.  You might  
be interested to check it out here:
http://mail.openjdk.java.net/pipermail/compiler-dev/2008-April/thread.html#300

The thread concerns an interest in improving the information about  
source location generated by the compiler, javac, and more  
specifically, increasing the resolution of the info from line-based  
coordinates to source-based coordinates. The submitter is also talking  
about using side files for the info, which (if I recall correctly) I  
have heard folk such as Jim discuss before now.

What would be the interest from the serviceability group about any  
such work? Is it "on your radar", "sometime eventually", or "it'll  
never happen"? :-)

-- Jon

P.S. Warning: the submitter has provided a patch on the compiler-dev  
thread but has not yet signed the SCA.
