Hi,
I opened the code, the NPE occurs here:
if (bytes != null) {
assert bytesRef != null;
bytesRef.decrementAndGet(); // <-- LINE 102, NPE occurs here
bytes = null;
bytesRef = null;
} else {
assert bytesRef == null;
}
This is completely impossible - can you enable assertions in your running JVM
to be sure ("-ea:org.apache.lucene..." JVM parameter)? It cannot be a threading
issue, because all this code is synchronized.
As you reported another issue with your JVM has segmentation faults, could it
be that you have a buggy JVM. Are you using the official Oracle ones, or is
this a modified one, e.g. by RedHat? If it is OpenJDK, it is better to use Java
7, as the Java 6 ones may not behave identical to Oracle's official JDKs and
may be more buggy.
Can you also post your full JVM version (java -version) and where you got it
from?
Uwe
