--------------------------------------

Thanks - we'll update to 2.9.3 for our latest version.  Hopefully all will be well then.

> I have a program, which does explicit commits.  On one occasion, I saw the following
exception thrown:
> java.lang.IllegalStateException: this writer hit an OutOfMemoryError; cannot commit
> at org.apache.lucene.index.IndexWriter.prepareCommit(IndexWriter.java:4061)
> at org.apache.lucene.index.IndexWriter.commit(IndexWriter.java:4136)
> at org.apache.lucene.index.IndexWriter.commit(IndexWriter.java:4114)
> In our program, we treat all errors as fatal and terminate the program (and restart).
 Runtime exceptions are sometimes handled differently, since they are usually indicative of
a programming bug that might be recoverable. in some situations.
> I think the OutOfMemoryError should not be wrapped as a runtime exception.. as this can
mask a serious issue from a fault-tolerant application.
