Andreas commented on PDFBOX-5241:
---------------------------------

Actually no - Calling this constructor is wrapped in an object which has a 
lifecycle itself (like a plugin).

The user says it happens every ~ 20th time when restarting the plugin.

You're definitely right, this is a weird issue.

We wrapped the call in a looping trying it several times to hopefully mitigate 
the problem. I'll let you know if it's reported again.

Thanks so far
