[Php-java-bridge-users] Method Overloading

I have a Java class that has multiple overloading methods.

For example:

fillReport(java.lang.String sourceFileName, java.util.Map<java.lang.String,java.lang.Object> params) 
fillReport(java.lang.String sourceFileName, java.util.Map<java.lang.String,java.lang.Object> params, java.sql.Connection connection) 
fillReport(java.lang.String sourceFileName, java.util.Map<java.lang.String,java.lang.Object> params, JRDataSource dataSource)

I want to use the third method signature, however php/java bridge is choosing the second method signature which is then causing an IllegalArguementException as follows:

PHP Fatal error:  Uncaught [[o:Exception]:"java.lang.Exception: Invoke failed: [[c:JasperFillManager]]->fillReport((o:JasperReport)[o:JasperReport], (i:Map)[o:HashMap], (i:Connection)[c:JREmptyDataSource]). Cause: java.lang.IllegalArgumentException: argument type mismatch

I think the problem occurs because the second and third methods final arguerment is both an object and the php/bridge code is only checking if it is an object?!?

How can I choose the appropriate method?

Much appreciated,

James
