maven - UnsupportedClassVersionError using Hudson 3.3.0 with Maven3 and Java 1.6 project -

i'm using hudson 3.3.0 java 7 jre run hudson since support java 6 runtime environment has been dropped hudson 3.3.0. (see: https://bugs.eclipse.org/bugs/show_bug.cgi?id=459703 )

besides configured java 6 jdk , i'm trying run job (maven 3.2.5) jdk. job fails after few seconds 'unsupportedclassversionerror' because eventspy classes compiled source level 1.7 , not working java 6 jdk:
