Thanks for the the update. Patching or fixing the synchronization in xmlbeans is an interesting idea. I haven't thought about that. I'll see if there is something that can be done for this in the xmlbeans code...

I'm wondering if there are any activities or plans for replacing xmlbeans with something else. I'm asking a) because the xmlbeans is retired and b) it has some issues in regards to memory usage and more important scalability.

Projects can be pulled out of the Attic if needed for a fix. So...

As mentioned here http://stackoverflow.com/a/34266795/812093 and as we also saw in our application in threadumps like the following xmlbeans is locking on the Locale object which leads to waits if multiple threads tries to create an XSSF workbook at the same time

If there was to be a fix for this, we could potentially petition the
Attic PMC to let us (i.e. POI+Tika) release XMLBeans 2.6.1 with the
threading fix in + a fix for the duplicate classes in the jar


Longer term though, as Andi says, we probably do want to move away
from xmlbeans, but there's no massive drive just yet
