Maia build # 10762 breaks previously working Grails project

I've been following along with Maia and exercising Grails functionality with it.  When I upgraded to build # 10762 today it broke my working Grails project.  I'm using Sun JDK 1.6.0_13, Grails 1.1.1, and Groovy 1.6.3.  Groovy has a dependency on ASM version 2.2.3.

I'm getting a NoClassDefFoundError for org.objectweb.asm.Opcodes

Information:Compilation completed with 1 error and 0 warnings
