Joshua Davies commented on JIBX-117:
------------------------------------
The issue appears to be the inclusion of two back-to-back "ordered=false"
structures inside another "ordered=false" structuer. Tracing through the code,
I beleive I've narrowed it down to line 305 of the file
build/src/org/jibx/binding/def/NestedStructure.java, in function
"genContentUnmarshal":
mb.freeSlot(FLAG_ARRAY_SLOT);
This will be invoked early, when the second structure completes its binding,
because of line 259 of the same function:
child.genContentUnmarshal(mb);
This will end up recursively calling itself, but it doesn't change the "mb"
(ContextMethodBuilder) parameter (and it doesn't look like it's supposed to).
When it completes (generating unmarshal for "element1"), it will execute line
305 on the containing contextMethodBuilder, remove the FLAG_ARRAY_SLOT, and
then the "for" loop that started on line 234 will continue on to try to
generate unmarshal content for "element2", but will throw a null pointer
exception when it no longer finds the "FLAG_ARRAY_SLOT".
I can see the issue, but I can't see how to resolve it; it seems like you'd
want to put off freeing the FLAG_ARRAY_SLOT until after you had processed
everything relative to the current ContextMethodBuilder, but I can't see any
way to figure out that you're at the "top" of the stack.
