Summary: SPARQL Updates get stuck on high concurrency of updates
Key: JENA-1683

Project: Apache Jena
Issue Type: Bug

While doing performance test of Jena Fuseki (latest release 3.10.0, using
jena-text for lucene index) with a mixed set of sparql-query and sparql-update
requests, I found that SPARQL_Update becomes unserviceable. SPARQL_Query still
functions normally. Sharing Screen shot of JMC JMX console where threads seem
to be WAITING infinitely for acquiring writer lock. !Screen Shot 2019-03-19 at
