Description
When sending fragment, then close and then another fragment, it fails with unclean close code, even though it should return 1000. In server log there can be seen ConcurrentModificationException [1]
This is regression in comparison to EAP 7.0.0.ER6 and this error occurs when running standard testsuite used commonly for websockets testing (autobahn testsuite, testcase 7.1.5 [2]). As such we are considering it to be a blocker.
Steps to reproduce:
- start EAP 7.0.0.ER7
- deploy attached websocket-endpoints.war
- run autobahn testsuite test 7.1.5 (wstest -m fuzzingclient -s fuzzing_client_spec.json, where fuzzing_client_spec.json contains [3]
- see server log and autobahn test report, where you can see it fails on getting clean close code
