[Soot-list] problem on anonymous class

[Eric Bodden]

Hi, Kouhei.

Thanks for reporting this. This is a known issue with the exception
checker. I am not quite sure while this bug still exists (I seem to
remember that it's actually a polyglot issue), but there is a debug
flag to disable checking of exceptions altogether:

-debug dontCheckExceptions
