Error running on IBM J9 VM(Java 1.6)

[ramyakrish85]

I am using grails 2.3.7 and trying to use IBM JVM .The application fails on start up because of the constraint plugin.My logs on startup is

Fatal error during compilation java.lang.ClassFormatError: JVMCFRE009 interface field must be public static and final; class=net/zorched/grails/plugins/validation/GrailsConstraintClass, offset=1396 (NOTE: Stack trace has been filtered. Use --verbose to see entire trace.)

Has anyone faced this?
