Instantiating top level pearSpecifier: reconfigure throwing NPE and need to set
Session
---------------------------------------------------------------------------------------
Key: UIMA-1466
URL: https://issues.apache.org/jira/browse/UIMA-1466
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Affects Versions: 2.2.2
Reporter: Marshall Schor
Assignee: Marshall Schor
Fix For: 2.3
A user reported these two issues when trying to run a top level pear. See
http://markmail.org/thread/jbacko4l6jyonzse
A discussion with Adam L indicates the problem may be being caused by the fact
that the PearSpecifier interface extends the ResourceServiceSpecifier, and
things would work better if it extended the ResourceCreationSpecifier - in that
the cause of the NPE which is a null value for the map representing the
configuration parameters, in the method
ConfigurationManagerImplBase.validateConfigurationParameterSettings. This map
is setup by Resource_ImplBase if the specifier is a subtype of
ResourceCreationSpecfier, but not otherwise.
Also, the *session* is setup, but again, only if the specifier is a subtype of
ResourceCreationSpecifier. So, the first thing to investigate is to see if we
can switch this, and what the impact would be.
