I can offer two tests and a diagnosis, and at least a suggestion for one or two
fixes.
== Tests ==
Try this:
- Set a breakpoint in TestResourceInterface_impl line 48
- Run ResourceManager_implTest in debug mode
- when the breakpoint is hit, inspect aData.getResourceManager() (is "null")
Admittedly, the external resource is not initialized in its natural environment
(within an AE) here.
Different test:
- Set a breakpoint in Apache uimaFIT
ExternalResourceFactoryTest$DummySharedResourceObject.load(DataResource) line:
558
- Run ExternalResourceFactoryTest.testScanBind() line: 103 in debug mode
- when the breakpoint is hit, inspect aData.getResourceManager() (is "null")
== Diagnosis ==
The ResourceManager_impl (line 567) would set a resource manager on the created
external resource, if one had been specified in the aResourceInitParams which
are handed down all the way from the creation of the analysis component to the
resource. But if the original called did leave it to UIMA to set up a resource
manager, this internally created manager is not passed through. Thus,
Resource_ImplBase.initialize (line 88ff) creates a new resource manager for the
resource.
This could be fixed by adding the following code in Resource_ImplBase line 176:
if (aAdditionalParams == null) {
aAdditionalParams = new HashMap<String, Object>();
}
if (!aAdditionalParams.containsKey(PARAM_RESOURCE_MANAGER)) {
aAdditionalParams.put(PARAM_RESOURCE_MANAGER,
mUimaContextAdmin.getResourceManager());
}
Additionally, ConfigurableDataResource_impl seems never to call
super.initialize(), so its mUimaContextAdmin is never initialized, hence any
getResourceManager() call returns null.

Btw., are there any general guidelines when to reply to Jira-issues via Jira
and when to simply reply on the list?
