Multithreaded model use?
Are the Model classes (subclasses of
opennlp.tools.util.model.BaseModel) guaranteed to be thread-safe? That
is, can I re-use the same SentenceModel in two different
SentenceDetectors and be sure there is no concurrency problems?
If this is true, please add this to the BaseModel javadoc.

Right, I'm loading models and caching them. Then each active use makes
its own ME and detector/tokenizer/etc. The model object is just a
passive bucket. It is essentially "final".
As to JIRAs: I'm used to much larger projects and JIRA pollution
becomes a problem. It's not like this is Open Relevance :)

Hi Jorn,
If they are thread-safe, what is there to fix? Are you just referring to
the documentation?
So, the models are thread-safe, but the detector,finder, tokenizer
objects are not?

They are thread safe. You are welcome to open a jira issue
and provide a patch to fix this.
