I think that Javassist is instrumenting field access incorrectly inside static 
methods (when the static method accesses an instance variable of an object 
passed as a parameter).  That's why it affects these $access methods so much 
... that's pretty much what those do.

The class that was affected has changed a bit since my first encounter with the 
problem. No, even though I've restored the inner class that spurred the problem 
in the first place, I'm no longer seeing the VerifyError.  I guess I'll post 
again if and when  it recurs.

 Yes, I think access$0 is generated by the normal compiler.

I'm going to try and reproduce this, and I'll upload the normal and enhanced 
.class files.

Hi,

The bytecode of access$0 in GridDataSopurce seems broken.
If access$0 is generated by Javassist, can you find the source
code given to Javassist for generating this method?

I don't think access$0 is not a method implicitly generated
by Javassist.

Thanks

And now I can see that the forum has truncated my (very long) message.  Here's 
the most relevant part at the end:


  | public void initializer();
  |   Code:
  |Stack=1, Locals=1, Args_size=1
  |0:   aload_0
  |1:   pop
  |2:   nop
  |3:   nop
  |4:   return
  |   LineNumberTable: 
  |line 23: 0
  |   LocalVariableTable: 
  |Start  Length  Slot  Name   Signature
  |0  5  0this   
Lorg/apache/tapestry/corelib/components/Grid;
  | 
  | public 
org.apache.tapestry.corelib.components.Grid(org.apache.tapestry.internal.InternalComponentResources,
 org.apache.tapestry.services.GridDataModelSource, 
org.apache.tapestry.services.BindingSource);
  |   Code:
  |Stack=2, Locals=4, Args_size=4
  |0:   aload_0
  |1:   invokespecial   #466; //Method java/lang/Object."":()V
  |4:   aload_0
  |5:   aload_1
  |6:   putfield#468; //Field 
org/apache/tapestry/corelib/components/Grid._$resources:Lorg/apache/tapestry/internal/InternalComponentResources;
  |9:   aload_0
  |10:  aload_2
  |11:  putfield#470; //Field

  |20:  invokevirtual   #474; //Method

  |23:  return
  | 
  | }
  | 

and here's the synthetic accessor method:


  | static org.apache.tapestry.grid.GridDataSource 
access$0(org.apache.tapestry.corelib.components.Grid);
  |   Code:
  |Stack=1, Locals=3, Args_size=1
  |0:   aload_0
  |1:   astore_1
  |2:   aconst_null
  |3:   astore_2
  |4:   invokespecial   #80; //Method 
org/apache/tapestry/corelib/components/Grid._$read_parameter_source:()Lorg/apache/tapestry/grid/GridDataSource;
  |7:   astore_2
  |8:   aload_2
  |9:   areturn
  |   LineNumberTable: 
  |line 26: 0
  |

Ah, never mind that note at the bottom, I found the compiler-generated code for 
access$0.


  | static org.apache.tapestry.grid.GridDataSource 
access$0(org.apache.tapestry.corelib.components.Grid);
  |   Code:
  |Stack=1, Locals=3, Args_size=1
  |0:   aload_0
  |1:   astore_1
  |2:   aconst_null
  |3:   astore_2
  |4:   invokespecial   #80; //Method

  |7:   astore_2
  |8:   aload_2
  |9:   areturn
