You could be on the right track because i get this error when i  
introduce a jump

Before

L0
Invokestatic gettransaction
Astore 1
L1
Aload 0
Aload 1
Invokespecial someconstructor
L2
Return
L3

After

L0
Invokespecial gettransaction
Astore 1
L1
Aload 0
Aload 1
Invokespecial someconstructor
Goto l1
L2

Both look fine to me, do you see something strange?

Ps
I'm working on adding some transaction advice on objects (including  
constructors) and i have removed all code that wasnt needed to  
reproduce the bug
