A javacc task that ran successfully under kaffe-1.1.4.PRECVS6-1 is now
failing under kaffe-1.1.4.PRECVS7-1. The kaffe install in question uses
the pthreads package, not jthreads. The javacc task is part of the
build for the lucene source package. A trimmed transcript of the build
attempt is attached at the end of the message.
The error appears to be related to garbage collection, and is highly
reproducible. For all transcripts, the -verbosegc switch was used on
java invocations. Executing the javacc task outside of Ant indicates
that the issue is not tied to the javacc task directly, since the task
completes without issue. The subsequent javacc task that should follow
can also be executed without issue. Transcripts of both are attached below:
