Peter Klügl commented on UIMA-3357:
-----------------------------------
Thanks for reporting this. I added a test for now.
The problem is that the type system has changed, at least its representation in
java, but nobody told the analysis engine about it. On the one hand, the
environment of the script stores the known types. This is initiated by
{{initializeTypes()}} either if the analysis engine was not initialized yet or
if the analysis engine is forced to update itself with each process call
(parameter reloadScript). On the other hand, the internal "indexing" (begin and
end map in RutaBasic) uses the current CAS, its annotations and their types. So
we have different type objects that cause problems.

> Key: UIMA-3357
> URL: https://issues.apache.org/jira/browse/UIMA-3357
> Project: UIMA
> Issue Type: Bug
> Components: ruta, uimaFIT
> Affects Versions: 2.0.1ruta, 2.1.0ruta
> Reporter: Daniel Maeurer
> Assignee: Peter Klügl
> Priority: Minor
>
> When running my Ruta script as an analysis engine in a pipeline, it does not
> work correctly when creating a new CAS and processing the pipeline a second
> time with the new CAS.
> While reusing the old cas with "cas.reset()" is working, creating a new CAS
> results in failing rules including "CONTAINS" in the ruta script.
> The ruta script used in the example:
> {code:title=mystic.ruta|borderStyle=solid}
> PACKAGE de.tudarmstadt.algo.vpino.ruta;
> DECLARE test;
> Document{CONTAINS(CW)->MARK(test)};
> {code}
> The following Java class can reproduce the error. It creates four xmi files.
> The last xmi file is missing the annotations created with rules including
> "CONTAINS".
