UseCase : setting property `jdk.serialFilter` as invalid and invoking Config.CreateFilter() twice.

Expected behavior : java.lang.ExceptionInInitializerError supposed to be thrown

Actual behavior : first invocation throws the java.lang.ExceptionInInitializerError and the second invocation throws java.lang.NoClassDefFoundError.

The java.lang.NoClassDefFoundError is unspecified anywhere in this context.

IMO we need to mention the possibility of java.lang.NoClassDefFoundError in the spec.

 Sample Code :
 ========
 
 Run the following with -Djdk.serialFilter=maxrefs=-123
 
        Assert.assertThrows(() -> Config.createFilter("maxdepth=2;maxrefs=5"), ExceptionInInitializerError.class );
        Assert.assertThrows(() -> Config.createFilter("maxdepth=2;maxrefs=5"), ExceptionInInitializerError.class );

And the second call would generate: Failed. None of the expected [java.lang.ExceptionInInitializerError] was thrown. java.lang.NoClassDefFoundError was thrown instead
