nullpointerexception after calling non-cached udf attached to struct key that was created with objectload

I went through the effort of making this easy to reproduce with standalone cfml example and ensuring I'm running latest version of lucee 4. This bug existed on Railo 4.2 too. I also determined that the bug is happening because the java property "this.properties.cachedWithin" is not null, and it should be null I guess since it's calling the wrong function, it should be calling _call on UDFImpl.java line 227 instead of the cachedWithin one. I don't understand how objectsave serializes internally, since it relies on quite a few classes, so I have given up trying to further understand how to patch it, for now. I assume that the issue is that objectsave is either not storing the null value, or objectload is not restoring it as null correctly. Hope this helps.
