>    Affects Versions: 2.0.0uimaFIT
>            Reporter: Richard Eckart de Castilho

> 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]
> java.lang.IllegalArgumentException: Parameter arguments have to come in key/value pairs, but found odd number of arguments [3]
> 	at org.apache.uima.fit.factory.ConfigurationParameterFactory.ensureParametersComeInPairs(ConfigurationParameterFactory.java:531)
> 	at org.apache.uima.fit.factory.ConfigurationParameterFactory.createConfigurationData(ConfigurationParameterFactory.java:374)
> 	at org.apache.uima.fit.factory.ExternalResourceFactory.createExternalResourceDescription(ExternalResourceFactory.java:277)
> 	at org.apache.uima.fit.factory.ExternalResourceFactory.createExternalResourceDescription(ExternalResourceFactory.java:213)
> {noformat}
> A workaround is currently to cast the first parameter name to Object:
> {noformat}
> createExternalResourceDescription(
>         MyResource,
>         (Object) MyResource.PARAM_VALUE, 
>         "myvalue"))
> {noformat}
