Hi,

im using java 1.5, spring and hibernate for my app.
now i encountered problems compiling my groovy-sources when i use generics.


here are the classes causing the problem:


class PagedAddressDataSource<T extends IAddressDataDao> implements
IPagedAddressDataSource {

  private T dao;
  ....
  public setDao(T){..}
}
class PagedDeAddressDataSource extends
PagedAddressDataSource<IDeAddressDataDao>{
  ....
}
***********************************
my pom.xml

<dependency>
       <groupId>org.codehaus.groovy.maven</groupId>
       <artifactId>gmaven-mojo</artifactId>
       <version>1.0-rc-2</version>
    </dependency>
    <dependency>
       <groupId>org.codehaus.groovy.maven.runtime</groupId>

doing a mvn clean test i get:

*******************************
seams something that has to do with generics is not supported:
"org.codehaus.groovy.maven.runtime.v15.StubCompilerFeature"

im new to groovy, so im not sure what exactly is going wrong.. :P

will this be solved in the near future? if not, any suggestions?

dont know if ist important, but all my interfaces must be written in
java because spring generates jdk-proxies.. e.g. the IPagedAddressDataSource


cheers,
Norbert
