> The commons.opennlp module can load the same model twice in parallel
> --------------------------------------------------------------------

> Key: STANBOL-1424
> URL: https://issues.apache.org/jira/browse/STANBOL-1424
> Project: Stanbol
> Issue Type: Bug
> Affects Versions: 0.12.0
> Reporter: Rupert Westenthaler
> Assignee: Rupert Westenthaler
> Priority: Minor
> Fix For: 1.0.0, 0.12.1
>
>
> The commons.opennlp model allows to load models by their names via the
> DataFileProvider infrastructure. Loaded models are cached in memory.
> If two components do request the same model in a short time. Especially when
> the 2md request for a model comes before the first was completed the same
> model is loaded twice in parallel. This will result that two instances of the
> model are loaded.
> While the 2nd request will override the cached model of the first the first
> component requesting the model might still hold a reference. In this case two
> instances of the model are holded in-memory.
> To solve those situations the OpenNLP service needs to use lock while loading
> models.
