Subject [jira] [Commented] (UIMA-5957) JCasIterable and JCasIterator in SimplePipeline should use the same ResourceManager
Date Mon, 14 Jan 2019 11:33:00 GMT

    [ https://issues.apache.org/jira/browse/UIMA-5957?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16741960#comment-16741960

Richard Eckart de Castilho commented on UIMA-5957:
--------------------------------------------------

The uimaFIT pipeline runners by default always create a new resource manager unless there
is an active UimaContext attached to the current thread. If this is the case, then its RM
is used (see DefaultResourceManagerCreator.newResourceManager()). So either you should ensure
that there is a UimaContext available or you'd need to implement your own ResourceManagerCreator.

> Using SimplePipeline with JCas cover classes and Ruta leads currently to class loader
switching for each annotator since the JCas and the annotator refer to a different uima class
loader due to the resource managers. Additionally, Ruta needs to perform internal reindexing,
which can lead to observed but undefined problems.
