                 URL: https://issues.apache.org/jira/browse/UIMA-5096

In

Example:
The following works:

ExternalResourceDescription geographicalResourceDescription = ExternalResourceFactory.createExternalResourceDescription(
					GeographicalResourceImplementation.class,
GeographicalResource.MAX_LENGTH_PARAMETER, String.valueOf(5),
);

Resource:
@ConfigurationParameter(name = MAX_LENGTH_PARAMETER)
private String maxLengthString;



The following fails:
Caller:
ExternalResourceDescription geographicalResourceDescription = ExternalResourceFactory.createExternalResourceDescription(
					GeographicalResourceImplementation.class,
GeographicalResource.MAX_LENGTH_PARAMETER, 5,
);

Resource:
@ConfigurationParameter(name = MAX_LENGTH_PARAMETER)
private int maxLength;



The exception is:
