6946751

[Alan Bateman]

Mark - I need to fix 6946751 as it currently prevents anyone from using 
jmod to install jmod packages that don't contain any class files (except 
for the module-info class of course). The issue seems to be the indexing 
that it done when installing. It looks like this can be easily fixed in 
SimpleLibrary.reIndex(ModuleId) so that it skips walking the classes 
when it doesn't exist. Is there anything else that I need to know to fix 
this?

Thanks,
Alan.
