Hi Andy,

The lines with pLaunchOptions have tabs instead of spaces.
jcheck has some complaints about tabs and trailing spaces.

Usually java applications use system properties, not environment variables.
I can see the need for access to PATH to find the tools, but a debugging 
flag seems like an outlier.
I suppose it is an undocumented implementation detail and does not need 
to be documented.

Thanks, Roger
