Javac working directory

           Summary: Javac working directory
           Product: Ant
           Version: 1.6.2
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Core tasks
        AssignedTo: dev@ant.apache.org
        ReportedBy: apacheant@goots.org


Modifying our current Ant build system to work with IBM's J9 JVM. This is a CDC
JVM which does not support all the command line options that javac supports. I
managed to almost get it working using the standard options - 
I had to set sourcepath to "" (it doesn't support that flag), specify the
executable, fork the process and use compiler=javac1.1 so that it doesn't use
the @files flag as that also isn't supported.
The one issue I found (currently I have hacked the source) was that when the
DefaultCompilerAdapter::executeExternalCompile function puts together the
command line it sets the working directory to the project base dir.
Due to the fact j9 does not support sourcepath flag, it is best to run it from
the root of your sourcetree so that any implicitly needed files are
automatically found. 
Therefore it would be really handy if there was a way to set the working
directory e.g. perhaps if sourcepath not set, and src is set then set working
dir to that.
