The CpeGui has been fixed - same issue. These fixes will be in the next
release.

I noticed when re-reading Jira issue 475 and Marisol's original note
that this happens also with the CpeGui - haven't yet addressed that.

Due to Eddie reproducing this problem and capturing a heapdump, we
tracked this down to something quite simple: The Document Analyzer
code has an instance field which holds the produced analysis engine.
This particular analysis engine loads 300 MB of stuff (the language
model) during its initialization, which happens when you do the
produceAnalysisEngine call.
So the line which looks like:
ae = UIMAFramework.produceAnalysisEngine(aggDesc);
causes a temporary condition where the "ae" is holding on to 300MB
from the old version of the analysis engine, while the new one is
trying to initialize - so you run out of memory.
The differences between Javas comes from the details of how the
String class is implemented - in the IBM 5 Java each string takes
more storage than in the Java 6.

found "SR3" mentioned in one file. The jar files are dated 2/1/2007.

Eddie,
so which JVM did you use to produce the problem? I understand
1.6.0_02 fixed it, but which one didn't work? Thanks.

Hi Marisol,
After installing opennlp on Apache UIMA v2.2.1, I was able to
reproduce
the
problem using OpenNLPParser with both documentAnalyzer and cpeGui.
However,
I had some problems reproducing this problem between an
environment with
the
2.2.1 SDK jars vs. a development environment using the latest code in
svn.
Turns out the difference between working and not working was the JRE.
JRE=
jre1.6.0_02 continued working on repeated runs.
Hope this can help you,
Eddie

I'm having a problem reallocating memory after

The cpeGui seems to have the same problem. I'm loading the OpenNLP
models
into a CPE for processing documents and if I want to setup another
process
without killing the GUI or the JVM the memory form the last CPE is
never
garbage collected.
Has anyone encountered this and is there a fix?
