Subject [jira] [Commented] (UIMA-5801) Performance degradation of jCas.reset when repeatedly used in different analysisEngines
Date Mon, 25 Jun 2018 21:06:00 GMT

    [ https://issues.apache.org/jira/browse/UIMA-5801?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16522814#comment-16522814

Richard Eckart de Castilho commented on UIMA-5801:
--------------------------------------------------

If UIMA core would take into account the context classloader, then we could stop uimaFIT from
creating classloaders all the time.

>          Issue Type: Bug
>          Components: UIMA
>    Affects Versions: 2.1

>
> The execution time of jCas.reset() increases linearly when invoked on the same jCas.
> This occurs in a loop that builds a new analysisEngine, processes the jCas and resets
it.
> This does not occur when the same analysisEngine is reused.
> A junit test demonstrating the behaviour is attatched.
