Burn Lewis resolved UIMA-5117.
------------------------------
Resolution: Fixed
Added a check for the saxon version as if saxon9 is in the classpath dd2spring
and uima-as will not work. The command-line syntax for the Transform method
was changed for saxon9, and it also causes a NPE in UIMA-AS when handling a
get-meta request.
The saxon9 check logs an error message and throws an exception:
03:58:05.163 - 1:
org.apache.uima.adapter.jms.service.Dd2spring.convertDD2Spring: SEVERE: saxon9
must not be in classpath
Caused by: org.apache.uima.adapter.jms.service.Dd2springException: saxon9 found
in classpath - dd2spring transformation and UIMA-AS do not support saxon9
:
Without this check the stack trace is:
04:14:57.222 - 48:

> UIMA-AS: dd2spring should log at INFO
> -------------------------------------
>
> Key: UIMA-5117
> URL: https://issues.apache.org/jira/browse/UIMA-5117
> Project: UIMA
> Issue Type: Bug
> Components: Async Scaleout
> Reporter: Jerry Cwiklik
> Assignee: Burn Lewis
> Fix For: 2.9.0AS
>
>
> Dd2Spring.convertDd2Spring() method should log exceptions at INFO level
> instead of CONFIG. When runtime was mis-configured, the code was failing yet
> there were no exceptions being logged, making debugging difficult.
> Also, when exception happens in converDd2Spring() it is not being re-thrown.
> This causes the uima-as to continue running and trying to deploy using
> zero-length spring context file which results in another Exception. Modify
> code to re-throw Exception.
