> Key: UIMA-3928
> URL: https://issues.apache.org/jira/browse/UIMA-3928
> Project: UIMA
> Issue Type: Bug
> Components: uimaFIT
> Affects Versions: 2.0.0uimaFIT
> Reporter: Richard Eckart de Castilho
> Priority: Major
> Fix For: 3.0.0uimaFIT

> The method
> {noformat}
> ExternalResourceDescription createExternalResourceDescription(
> Class<? extends SharedResourceObject> aInterface,
> String aUrl,
> Object... aParams)
> {noformat}
> can be invoked if the user actually wanted to call the method
> {noformat}
> ExternalResourceDescription createExternalResourceDescription(
> Class<? extends Resource> aInterface,
> Object... aParams)
> {noformat}
> E.g.
> {noformat}
> createExternalResourceDescription(
> MyResource,
> MyResource.PARAM_VALUE,
> "myvalue"))
> {noformat}
> Java seems to be smart enough to invoke the correct method, but when calling
> this from Groovy, it fails:
> {noformat}
> Caught: java.lang.IllegalArgumentException: Parameter arguments have to come
> in key/value pairs, but found odd number of arguments [3]

> {noformat}
> A workaround is currently to cast the first parameter name to Object:
> {noformat}
> createExternalResourceDescription(
> MyResource,
> (Object) MyResource.PARAM_VALUE,
> "myvalue"))
> {noformat}
