Re: [cglib-devel] IllegalAccessError in fastclass
I'm copying Geronimo dev on this so, Jason Dillon can respond with more specifics. To get the ball rolling, here is the top of the stack trace we are seeing: java.lang.IllegalAccessError: tried to access class org.springframework.ejb.support.AbstractEnterpriseBean from class com.solidusnetworks.paycore.ach.model.merchant.service.MerchantViewServi ceBean$$FastClassByCGLIB$$e322b03a at com.solidusnetworks.paycore.ach.model.merchant.service.MerchantViewServi ceBean$$FastClassByCGLIB$$e322b03a.invoke(generated) at org.openejb.dispatch.AbstractMethodOperation.invoke (AbstractMethodOperation.java:90) at org.openejb.slsb.RemoveMethod.execute(RemoveMethod.java:69) at org.openejb.dispatch.DispatchInterceptor.invoke (DispatchInterceptor.java:72) The target bean is MerchantViewServiceBean and the method we are calling is ejbRemote(), which is part of the javax.ejb.SessionBean interface. MerchantViewServiceBean does not have its own ejbRemote (), it picks it up from AbstractStatelessSessionBean (from app), which picks it up from AbstractStatelessSessionBean (from spring). -dain On Feb 14, 2006, at 1:10 PM, Chris Nokleberg wrote: On Tue, Feb 14, 2006 at 12:31:45PM -0800, Dain Sundstrom wrote: I'm getting an IllegalAccessError when using fastclass to invoke a method on an instance where the method is inherited from a parent class. This works in general, so it must be something particular about your child/parent classes. What is the method declaration, and the package/access of the respective classes?

I've reproduced the bug. It is caused because the method is actually defined in a non-public class in another package: the public class org.springframework.ejb.support.AbstractStatelessSessionBean extends the non-public class org.springframework.ejb.support.AbstractSessionBean. IMHO this is kind of weird on Spring's part, but nonetheless it has exposed a bug in FastClass, which is calling invokevirtual on the ancestor class instead of the derived class. The workaround, as you have discovered, is to redefine the method in the derived class, even if it is just to call super.ejbRemove(). Some other parts of CVS HEAD are in transition now (the MethodInterceptor startup optimizations) so even after I fix this bug you'll have to wait a little while. I'll let you know when there is a new version to test. Thanks, Chris
Re: [cglib-devel] IllegalAccessError in fastclass
Weird... I did not notice that org.springframework.ejb.support.AbstractSessionBean was package private. It makes a little sense that is is package private because you only expect users to extend from one of its direct subclasses for MDB or a SB. Thanks for taking a look :-) I've added definitions for ejbRemove() which call super.ejbRemove() to get around this. Do you know when the fix will make it into a CGLIB release that would be usable by G? --jason On 2/14/06, Chris Nokleberg [EMAIL PROTECTED] wrote: On Tue, Feb 14, 2006 at 12:31:45PM -0800, Dain Sundstrom wrote: I'm getting an IllegalAccessError when using fastclass to invoke a method on an instance where the method is inherited from a parent class.
