[Scons-users] IndexError in Java parser with anonymous classes

[Bill Deegan]

Will,

Can you try 2.4.0 or the default branch?
I checked your stack trace and the line numbers don't entirely match up
with current default, so its possible there are some changes which may
affect your issue, and if nothing else will make it easier to look at the
stacktrace/code.
