Summary

0004551: ejb: invalid proxy code generation with generics

Description

I have bean with method methods, which using generics:

public <DO> DO getById(final Class<DO> clazz, final long id) throws NotFoundException
and
public <DO> Collection<DO> listAll(Class<DO> clazz, boolean withDeleted);

This generated to stateless proxy java-code:

public <T_0 extends java.lang.Object>
T_0 getById(java.lang.Class<T_0> a0, long a1)
throws org.dicr.util.data.exc.NotFoundException;
and
public java.util.Collection<T_0> listAll(java.lang.Class<T_0> a0, boolean a1)

First is Ok, but seconds is inccorrect and this code can't be compiled:

cannot find symbol
symbol : class T_0

Second methos must be traslated in the same way as first:

public <T_0> java.util.Collection<T_0> listAll(java.lang.Class<T_0> a0, boolean a1)
instead of
public java.util.Collection<T_0> listAll(java.lang.Class<T_0> a0, boolean a1)

Notes
(0005245) dicr 05-15-11 11:10	<T_0> is absent in generated method listAll. Seems this problem is presend, when return type is Collection<T>, and not present when return type is T.

(0005246) dicr 05-15-11 16:08	I tested with another return type - array: public <DO extends BaseEntity> DO[] listAll(Class<DO> clazz, boolean withDeleted) in MyBean_StatelessProxy.java transleted to: public T_0[] listAll(java.lang.Class<T_0> a0, boolean a1) should be: public <T_0> T_0[] listAll(java.lang.Class<T_0> a0, boolean a1) Generics collections return in bean method not supported by resin, but return with single generics type working.
