Revision 949509 (LUCENE-2480) causes IOE "read past EOF" when processing older
format SegmentInfo data when JVM assertion processing is disabled.
-------------------------------------------------------------------------------------------------------------------------------------------------
Key: LUCENE-2497
URL: https://issues.apache.org/jira/browse/LUCENE-2497
Project: Lucene - Java
Issue Type: Bug
Components: Index
Affects Versions: 4.0
Environment: Any JVM running without assertions enabled (such as
Tomcat by default)
Reporter: Kevin Dana
At revision 949509 in org.apache.lucene.index.SegmentInfo at line 155, there is
the following code:
if (format > SegmentInfos.FORMAT_4_0) {
// pre-4.0 indexes write a byte if there is a single norms file
assert 1 == input.readByte();
}
Note that the assert statement invokes input.readByte();
If asserts are disabled for the JVM, input.readByte() will not be invoked,
causing the following readInt() to return a bogus value, and then causing an
IOE during the (mistakenly entered) loop at line 165.
This can occur when processing old format (format "-9") index data under Tomcat
(whose startup scripts by default do not turn on asserts).
Full stacktrace:
