-----------------------------------
Summary: UIMA-AS: JMX registration of MBean fails when name is
invalid
Key: UIMA-5714
URL: https://issues.apache.org/jira/browse/UIMA-5714
Project: UIMA
Issue Type: Bug
Components: Async Scaleout
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Fix For: future-Uima-AS
When registering UIMA-AS MBean with JMX a unique name (ObjectName) is
constructed at runtime. Part of this name comes from AE resource specifier and
fetched via
((ResourceCreationSpecifier) resourceSpecifier).getMetaData().getName();
Since users can type whatever they want for the name, this string has to be
sanitized to remove chars that are not compatible with jmx ObjectName.
In one concrete scenario, a user included comma in the name which is not a
legal char for ObjectName. This caused an exception during initialization of a
service:

In BaseAnalysisEngineController.setupName() make sure the name contains only
valid chars for ObjectName. Code in question is this:
String serviceName = ((ResourceCreationSpecifier)
resourceSpecifier).getMetaData().getName();
