Disabling JIT compiler. Reflective Optimizer will be used. This is more of an MVEL question, I guess, but do you know if there is a way to force the use of reflection over ASM?

Can you tell me what class it is that gives the nosuchmethod? (ie what the target class is) and we can make sure all references are to inlined one so this won't happen again. Michael.

Mark brad hadfield wrote: Hi, I wonder if anyone could help me? I'm attempting to use the 'from' keyword in the same fashion as the sample found on the Release Notes/Language Improvement wiki. The example shows a piece of syntax that uses the 'from' keyword to obtain data via a Hibernate query. i.e: $r : Restaurant( $postCode ) from hbSession.getNamedQuery( "some query" ).setProperties( [ key1 : value2, key2 : value ] ).list() I'm having difficulty executing syntax using this keyword because Hibernate uses CGlib which relies on ASM 1.5.3 - the 'from' keyword seems to rely on MVEL which uses ASM 3.0. ASM 3.0 is not backwards compatible with ASM 1.5.3 and I get 'no such method' errors. So how does one get the 'from' keyword to work in an environment running Hibernate?
