Hi Mandy,

Thanks for looking at this.

Go ahead and push your patch first.

I'll then update my patch with needed jdk.internal.reflect.ClassFileAssembler::emitMagicAndVersion changes.

Looks good.

jdk.internal.reflect.ClassFileAssembler::emitMagicAndVersion will need to be updated too after I push the fix for JDK-8207790. We can follow up separately depending on which patch goes first. Mandy On 7/18/18 11:43 AM, Harold David Seigel wrote: Hi,

Please review this LWorld change to ignore the ValueTypes attribute and value type specific access flags for class file versions < 55.  This fix also includes changes to the verifier to throw VerifyError exceptions for withfield and defaultvalue opcodes for class file versions < 55. Open Webrev: http://cr.openjdk.java.net/~hseigel/lworld.cfpverf/webrev/ The changes were tested with various tier1 - tier5 Mach5 tests on Linux and Mac. Thanks, Harold
