The XStream library used internally tries to do reflection to convert between some custom java objects and XML, and this can block when it tries to log "illegal access" to disk.

To reproduce:

cd server/rest
taskset -c 0,1 mvn -DforkMode=never -DforkCount=0  test

sometimes causes the test NonIndexedPojoQueryTest.testReadDocumentFromBrowser to fail
