Sergey Beryozkin commented on CXF-5853:
---------------------------------------
This was caused by the same thread injecting a context and then, while
processing another entity which is not supported by Jackson, setting the
context to null too early - but when the original entity was processed
afterwards we were getting NPE.
> Mutlipart JAXB model + InputStream using JacksonJsonProvider cause NPE
