This gives > information only about failed lock, but lacks the "whole picture". > Proposed change: in case of lock failure, factory should dump out all lock > states (may be huge on big builds), as that would allow simpler > identification of possible problems. All this could be sorted out at "high > level" (so no need to fiddle with file locks, hazelcast or redisson), but for > memory constraints it should NOT be enabled by default, this "diagnostic" > should be turned off by default, but possible by users to turn on if needed. -- This message was sent by Atlassian Jira (v8.20.10#820010)
