Deadlock for some Query objects in the equals method (f.ex. PhraseQuery) in a
concurrent environment
----------------------------------------------------------------------------------------------------
Key: LUCENE-1358
URL: https://issues.apache.org/jira/browse/LUCENE-1358
Project: Lucene - Java
Issue Type: Bug
Components: Other
Affects Versions: 2.3.2
Reporter: Torbjørn Køhler
Priority: Minor
Attachments: TestDeadLock.java
Some Query objects in lucene 2.3.2 (and previous versions) have internal
variables using Vector. These variables are used during the call to the
equals method. In a concurrent environment a deadlock might occur. The
attached code example shows this happening in lucene 2.3.2, but the patch in
LUCENE-1346 fixes this issue (though that doesn't seem to be the intention of
that patch according to the description :-)
