Hello!

I'm not sure if the problem that I have can be solved by myself, because it seams to be a bug of Seam. But anyway, perhaps someone can help me get along with the following problem:

I have this method defined in an EntityBean:

private int[][] LCS( List<String> original, List<String> modified ) { ... }

When I try to run a TestNG SeamTest I get the following error before the test starts:

ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController] Error installing to Start: name=persistence.units:jar=test-build.jar,unitName=KiWi state=Create
java.lang.IllegalArgumentException: No PropertyTypeExtractor available for type void 
     at org.hibernate.annotations.common.reflection.java.JavaReflectionManager.toXType(JavaReflectionManager.java:164)
     at org.hibernate.annotations.common.reflection.java.JavaXMethod.create(JavaXMethod.java:18)
     at org.hibernate.annotations.common.reflection.java.JavaReflectionManager.getXMethod(JavaReflectionManager.java:128)
     at org.hibernate.annotations.common.reflection.java.JavaXClass.getDeclaredMethods(JavaXClass.java:114)

It was caused because of the return type of the method above.
After searching for the Exception-Information-Text I figured out that the problem may be caused by the following method in the JavaXFactory class:

public JavaXType toXType(TypeEnvironment context, Type propType) {
          Type boundType = toApproximatingEnvironment( context ).bind( propType );
          if ( TypeUtils.isArray( boundType ) )
               return new JavaXArrayType( propType, context, this );
          if ( TypeUtils.isCollection( boundType ) )
               return new JavaXCollectionType( propType, context, this );
          if ( TypeUtils.isSimple( boundType ) )
               return new JavaXSimpleType( propType, context, this );
          throw new IllegalArgumentException( "No PropertyTypeExtractor available for type void ");
     }

The full class can be found here:

Does anyone now how I can solve my problem? Is it related to hibernate or Seam?

Thanks a lot! Steffi
