Defer justification: it is not 7u45 regressions (it was introduced in 7u25), so lets fix it in 7u51

Seems appeared after changes for JDK-7127486. JNLPClassLoader.getJarDescFromURL(url) returns null. + // Get the URL this JAR file and add permissions to read all JARs + // that are retreived from the same host. This is to provide the + // same semantics as the SocketPermission gives for HTTP URLs + JARDesc jd = getJarDescFromURL(url); + + // store jar version in app context map for use in DeployManifestChecker + ToolkitStore.get().getAppContext().put(Config.APPCONTEXT_KEY_PREFIX + + url.toString(), jd.getVersion());
