------------------------------------------
Summary: BasicMetricExporter has inconsistent synchronized access
to field `configuration`
Key: IGNITE-21691
URL: https://issues.apache.org/jira/browse/IGNITE-21691
Project: Ignite
Issue Type: Task
Reporter: Viacheslav Blinov
Issue detected by SpotBugs but is also highlighted by Idea inspection.
Specifically the warning reported is:
{noformat}
M M IS2_INCONSISTENT_SYNC IS: Inconsistent synchronization of
org.apache.ignite.internal.configuration.ConfigurationNode.invalid; locked 66%
of time Unsynchronized access at ConfigurationNode.java:[line 138]{noformat}
{noformat}
M M IS2_INCONSISTENT_SYNC IS: Inconsistent synchronization of
org.apache.ignite.internal.configuration.ConfigurationNode.val; locked 60% of
time Unsynchronized access at ConfigurationNode.java:[line 145]{noformat}
Fields `val` and `invalid` are accessed in both synchronized and unsynchronized
fashion. This can be a source of hard to catch bug.
Investigate whenever this is a false-positive and we should suppress it, or we
should make a proper fix.
At the result of investigation corresponding TODO should be removed in
spotbugs-excludes.xml
