This version builds with Java 6. I tried to bump it myself, but I got lost in a maze of twisty little bundled jars, all different, and also there doesn't seem to be a source download of the api package, only a precompiled one, from http://jcp.org/aboutJava/communityprocess/mrel/jsr224/index2.html
jax-ws 2.1.5 needs tools.jar to compile
this packages were removed per bug 566232
