Description

In a Spring Boot application,  we get a lot of NPE, with only four REST clients asking to produce pdf continuosly. In attachment example spring boot app, stacktrace and input files (issue is indipendent from this test files).

example call to endpoint:
curl -X POST "http://localhost:8080/pom/render/fopUncompressed" -H "accept: application/pdf" -H "Content-Type: multipart/form-data" -F "xsl=@20sm2019render_fop.xsl;type=text/xml" -F "xml=@20sm2019render_fop.xml;type=text/xml" 
on windows dev pc, using jmeter, I can reproduce the issue occasionally, last test with 30 concurrent threads producing 3000 pdf files shows only 2 NPE.

In the openshift production enviroment with less concurrent clients, the issue is disruptive.
