Fixed long term failing unit-test, fixed NPE from ClassLoader

* netx/net/sourceforge/jnlp/NullJnlpFileException.java: new class to
distinguish plain NPE from null jnlp file.
* netx/net/sourceforge/jnlp/SecurityDesc.java: (getSandBoxPermissions)
added throw of NullJnlpFileException in case of null jnlp file.
* netx/net/sourceforge/jnlp/runtime/JNLPClassLoader.java: (findClass)
added Override annotation,  add catch of NullJnlpFileException and
re-throw of  CNF exception.
* tests/netx/unit/net/sourceforge/jnlp/runtime/CodeBaseClassLoaderTest.java:
(testResourceLoadSuccessCaching) (testResourceLoadFailureCaching)
(testParentClassLoaderIsAskedForClasses) - internal JNLPFile's
(getSecurity) null in SecurityDesc constructorrepalced by this.
(testNullFileSecurityDesc) new test to ensure NPE in null JNLPFile case.
