Description Svata Dedic 2000-09-27 10:41:24 UTC

Reported on behalf of Marek.Fukala@netbeans.com:

During execution of Marek's automated compiler test, the Internal compiler
sometimes throws NullPointerException and fails to compile a source.

The stacktrace is:
java.lang.NullPointerException

Comment 1 Svata Dedic 2000-09-27 10:51:59 UTC

There was a race condition during initialization of the Internal Compiler and
the parser engine.

Resolved for 3.4.x or earlier, no new info since then -> closing.
