NIOFSDirectory AssertionError in sun.nio.ch.NativeThreadSet
I've been running some tests with Lucene 2.9.1 on a Linux box with a
Sun JVM and getting a sun.nio.ch.NateiveThreadSet Assertion error (see
below for stacktrace).
Does anyone know what this error means? Any suggestions for a workaround?
We used the following to open the index.
FSDirectory dir = FSDirectory.open(new File("path_to_lucene_index"));
IndexReader sReader = IndexReader.open(dir, true); // open a
read-only reader
java version "1.5.0_08"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_08-b03)
Java HotSpot(TM) Server VM (build 1.5.0_08-b03, mixed mode)

Posted by Uwe Schindler <uw...@thetaphi.de>.
Maybe you should update your JVM?
1.5.0_08 is really old, the latest 1.5 version is _22. This looks like a Sun
Bug, because the AssertionException happens in Sun's code not in Lucene's.
