I have worked on a new icedtea 3 patch:
http://old.nabble.com/file/p35272149/icedtea-3-openjdk-8-b80-jamvm.patch
icedtea-3-openjdk-8-b80-jamvm.patch 

This time OpenJDK 8 gets built using the JamVM libjvm.so and yes i agree
something with "default methods" in OpenJDK 8 break the build, at least i
see a related missing JVM_IsVMGeneratedMethodIx method during linking:
