Ryan - do you have a test case that demonstrates the issue with the main 
line (jdk/jdk)? I think we need that in order to study this issue a bit 
more closely and see what options are available. I see Paul has pasted 
in a stack trace from January and I think it would be interesting to see 
what command line options were used. I don't have a good sense yet how 
this might be fixed but it may need work in FilePermission and/or 
initializing the default file system provider at a different time during 
the startup.
