Re: Phantom classes and analysis

[Feng QIAN <fqian@sable.mcgill.ca>]

Hi Eric,

I am not sure the designing logic of only allowing phantom class created
in "loadClassAndSupport". All things happen in Scene.java between line 350
to 388. We can wait for other people's answer, but certainly you can work
around this problem temporarily by calling setPhantomRefs(true) in
getSootClass.

Cheers,
Feng
