Subject [jira] [Commented] (UIMA-5097) Current component info on CAS not reset
Date Thu, 01 Sep 2016 15:12:20 GMT

    [ https://issues.apache.org/jira/browse/UIMA-5097?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15455728#comment-15455728

Richard Eckart de Castilho commented on UIMA-5097:
--------------------------------------------------

When I change back to uimaj-core 2.6.0 (and remove calls to withSnapshotIterator(), introduce
some explicit type casts no longer necessary with the generics-enabled UIMA versions, and
remove references UimaContextHolder from uimafit trunk), that case seems to work again. Debugging
yields that componentInfo is null at the time in question with 2.6.0.

Another test fails then because back in 2.6.0 it was still possible to add an FS multiple
times to an index - so that seems entirely unrelated.

> uimaFIT tests re-use a single CAS which is stored in a thread-local variable and reset
that CAS between unit tests. Apparently there was some change which causes the Sofa-mapping
information - or more specifically the current component info from which that mapping is obtained
- to not be reset anymore. The problem only appears when running all uimafit-core tests jointly
in one JVM, e.g. from Eclipse.
> Initial hypothesis which proved to be wrong: 
> There may be a bug that might be related to the UimaContextHolder not being cleaned up
probably (probably in case of some kind of failure).
> The problem appears when running the uimafit-core tests in Eclipse. Here all tests run
in the same JVM instance which allows "global" information like thread locals to be carried
over between unit tests.
> Then running all tests and when the `ViewCreatorAnnotatorTest` runs before the `SimplePipelineTest`,
then the deserialization of an XMI file fails because `_InitialView` is still mapped to `myView`
in the UIMA context. Debugging yields that the UIMAContext in use for the SimplePipelineTest
apparently still belongs to the `ViewCreatorAnnotatorTest` because the *mQualifiedContextName*
is `/org.apache.uima.fit.component.ViewCreatorAnnotatorTest$SofaAwareAnnotator/`
> This hypothesis was wrong: checked it by verifying that UimaContextHolder.getContext()
is null before and after each unit test.
