      extended by wcs.ProcessTask
          extended by wcs.JLexTask
All Implemented Interfaces:
Runnable

public class JLexTask
extends ProcessTask

task to run a patched version of JLex. The patch provides processing of standard input if there is no command line argument, it redirects the commentary to diagnostic, rather then standard output, and it returns exit code 1 on error. BUG: this should not use ProcessTask.
