Message:
add a test case for cyclically defined objects This commit contains a failing test case. It contains a stream with a /Type entry that is an indirect reference to an object defined as itself: obj 8 0 8 0 R endobj The implementation of resolve() does not properly detect cycles and runs into an infinite loop.
