Null Pointer Exception when launching Web Start applications https://bugs.openjdk.java.net/browse/JDK-8153736 (Duplicate bug JDK-8154155) This bug was found in b113 and is expected to be fixed in 9 ea-115 (build 115) all being well.

fix is in getJarIndex (line 66). replace: return new JarIndexWrapper(jarIndex); with: return jarIndex == null ? null : new JarIndexWrapper(jarIndex);
