[wildfly-dev] Analysis of wildfly-8.1.0 dependency on JDK-Internal APIs

[Rebecca Searls]

I ran jdeps on apache CXF ( http://git-wip-us.apache.org/repos/asf/cxf.git,  branch 3.0.x-fixes)
and got the following results.

---
digraph "ehcache-2.8.1.jar" {
    // Path: ./services/sts/sts-war/target/SecurityTokenService/WEB-INF/lib/ehcache-2.8.1.jar
   "net.sf.ehcache.pool.sizeof.UnsafeSizeOf"          -> "sun.misc.Unsafe (JDK internal API (rt.jar))";
}
	
---
digraph "woodstox-core-asl-4.3.0.jar" {
    // Path: ./services/sts/sts-war/target/SecurityTokenService/WEB-INF/lib/woodstox-core-asl-4.3.0.jar
   "com.ctc.wstx.msv.GenericMsvValidator"             -> "org.relaxng.datatype.Datatype (JDK internal API (tools
.jar))";
}
