I found the reason for the problem:
try {
writer = new IndexWriter(dir, newIndexWriterConfig(
TEST_VERSION_CURRENT, new MockAnalyzer())
.setMergeScheduler(new SerialMergeScheduler()) // no threads!
);
// TODO: Make IndexWriter fail on open!
if (random.nextBoolean()) {
writer.optimize();
} else {
reader = writer.getReader();
}
fail("IndexWriter creation should not pass for "+unsupportedNames[i]);
} catch (IndexFormatTooOldException e) {
// pass
} finally {
if (reader != null) reader.close();
reader = null;
if (writer != null) writer.close();
writer = null;
}
This test checks that an old index somehow fails to open docstore. As
IndexWriter does not do this on open (see TODO), it trys to open Reader or
optimize(). Since Mike's commit for LUCENE-2618, the optimize call seems to be
somehow delayed until close() is called, where the Exception is thrown again.
We should simply ignore it there. So when close of already broken IndexWriter
fails, its not a problem.
