hi,
environment: lucene 2.4, jdk 1.6
i'm using quartz jobs to schedule indexing tasks; currently i'm creating a
new instance of an analyzer each time i open the index; after some time i'm
getting a out of memory;
Analyzer Class:
private ThreadLocal tokenStreams;
since the analyzer class is using a thread local -> should i reuse an
analyzer (e.g singleton pattern) in this case (quartz job reusing threads
(=tread pool) -> thread local data never gets freed)...)?
Mem dump:
