Summary: NullPointerException in LL

Initial Comment:
Filed on behalf of DXN:

I can now reproduce the error, which is I think is LL related.
Please see attached.
If you look at the method IntList subst(int oldN, int newN) of the classes
IntList, ConsIntList and EmptyIntlis, I mistyped IntList as InList.  The
drjava could not locate the class InList and choked.

Zung

OK, this time, I clicked the Compile button and these came up:

In the compiler output pane:

1 error found:
File: (no associated file)  [line: (no source location)]
Error: java.lang.NullPointerException

Error pop-up dialog:
