Ok, got it,
The version of the compiler shipped with b65 has lambda disabled with a 
non standard flag
   /usr/jdk/jdk1.8.0/bin/javac -XDallowLambda Test.java

changeset 01c9d4161882 enable lambda by default:
http://hg.openjdk.java.net/jdk8/jdk8/langtools/diff/01c9d4161882/src/share/classes/com/sun/tools/javac/parser/JavacParser.java
so b66 will have lambda enabled by default.
