This occurs in the context of Apache ManifoldCF, which is using Tika to extract
document content from a variety of different document types, which in turn is
using Apache POI. ManifoldCF uses a fairly common tiered classloader setup,
and has all the POI jars at the same level along with many others. The basic
expectation is that the classloader that was used to load a class should be
used to load any class it depends on, whether directly or via reflection. But
unfortunately it appears that there's a place in POI where this isn't honored,
and instead the wrong class loader is used.
A similar ticket was opened about a year ago for the POI project, related to
how xmlbeans did its reflection class loading, and that was successfully
resolved. This seems to be another similar situation.
The place where this occurred was in a production system whose documents I do
not have access to. It would be good to know what type of document it was as
well.
