RFR: 8015145: Smartjavac needs more flexibility with linking to sources

[Kumar Srinivasan]

Hi Erik,

So what else needs to be done for this ?  I take it this has been 
reviewed by Jon
who is the most familiar with it. If all it takes is someone to sponsor 
this push,
I can do so, let me know.

Thanks

Kumar
