ASMOperation.java

					case Bytecode.DUP:
						s = stack[fp - 1]; // fp is 0!!!
						stack[fp++] = s;
						break;

Caused by: java.lang.ArrayIndexOutOfBoundsException: -1
at org.eclipse.m2m.atl.engine.emfvm.ASMOperation.exec(ASMOperat ion.java:493)
... 30 more

Some more information - I managed to get some stack trace and this error seems to happen when abstract rule is called - it seems to do some crazy calls:

__matchAbstractCreateIqConfig:12    call B.not():B
    locals: self=TransformUsV1ToImplConfig : ASMModule, iq=xml!testalloptions    Calling true.not()
    stack: false
    locals: self=TransformUsV1ToImplConfig : ASMModule, iq=xml!testalloptions
__matchAbstractCreateIqConfig:13    if 190
    stack: 
    locals: self=TransformUsV1ToImplConfig : ASMModule, iq=xml!testalloptions
__matchAbstractCreateIqConfig:14    dup
