xdoclet ojb.reference property class-ref doesn't work with generics

There is bug inside xdoclet-ojb-module, which cause it to crash when parsing classes using generics feature.

Here is example code:

package some.package;

/**

• @ojb.class
  */
  class Foo {
  }

/**

• @ojb.class
  */
  class Bar<T extends Foo> {
  /**
• @ojb.reference class-ref="some.package.Foo"
• foreignkey="someReferenceId"
• database-foreignkey="false"
• auto-retrieve="true"
• auto-update="none"
• auto-delete="none"
  */
  private T someReference;

/**

• @ojb.field
  */
  private Integer someReferenceId;
  }

I skiped some elements, to make this example shorten.
xdoclet craches when tries to find T class, which doesn't exist of course.
