Hi.
It's a bug in Jackrabbit fixed in the latest version. The current
workaround is to temporarily increase the per thread stack (-Xss) in
the JVM, returning it to normal after the import. Hopefully the fix
will either be backported into versions of Jackrabbit Magnolia uses
or Magnolia will move to a fixed version.
Yup, it's been fixed for 1.5 [1], which afaik hasn't been released
yet, so this won't happen before the next major Magnolia release. In
the meantime, we're hoping they'll backport the fix to the 1.4 branch
and release 1.4.6 soon.
Cheers,

An update -
I set a breakpoint and trapped the exception.
This seems to be happening because there is a very, very deep
structure of NameSpaceContext objects - these objects have a
"parent" pointing to another NameSpaceContext object, and nothing
at all in their "prefixToUri" or "UriToPrefix" hashmaps. As far as
I can tell the parent objects are all different (it's not a
circular link) - but I've only followed it about 20 levels in - I
don't know deep the rabbit hole goes, maybe there's a circular link
further down.
The name it seems to be trying to resolve is "jcr:primaryType".
The last bit of magnolia code I can see on the stack is
ImportXmlRootFilter.startElement:141
SkipNodePropertyFilter.startElement:148
XMLFilterImpl.startElement:527
VersionFilter.startElement:120

etc.
I'm afraid for some reason the log doesn't contain the top of the
stack so I can't see what bit of magnolia we're in at the time.
I tried deleting the node that it was currently working on from
the xml file, but I still get the same issue (with the node
deleted it crashes on the next node).
Any ideas ?
