Symptoms

Trying to POF-serialize a collection which has null elements via PofBufferWriter and its methods:

• writeCollection()
• writeMap()
• writeObjectArray()
• writeLongArray()

fails with NullPointerExceptions.

However, null values are actually allowed in such collections, so they should also be handled in a way that the collection does not break.
