Subject [jira] Created: (LUCENE-1171) Make DocumentsWriter more robust on hitting OOM

Make DocumentsWriter more robust on hitting OOM
-----------------------------------------------

                 Key: LUCENE-1171
                 URL: https://issues.apache.org/jira/browse/LUCENE-1171
             Project: Lucene - Java
          Issue Type: Bug
          Components: Index
    Affects Versions: 2.3
            Reporter: Michael McCandless
            Assignee: Michael McCandless
            Priority: Minor
             Fix For: 2.4


I've been stress testing DocumentsWriter by indexing wikipedia, but not
giving enough memory to the JVM, in varying heap sizes to tickle the
different interesting cases.  Sometimes DocumentsWriter can deadlock;
other times it will hit a subsequent NPE or AIOOBE or assertion
failure.

I've fixed all the cases I've found, and added some more asserts.  Now
it just produces plain OOM exceptions.  All changes are contained to
DocumentsWriter.java.

All tests pass.  I plan to commit in a day or two!
