(solr) 01/03: SOLR-17857: SolrMetricsContext is now reliably closed (#4226)
This is an automated email from the ASF dual-hosted git repository.

commit aa2e32da881aa6aafcfa82cdb079f79ea4855f23

SOLR-17857: SolrMetricsContext is now reliably closed (#4226)
SolrMetricsContext is now AutoCloseable; renamed unregister() to close().
Ensure it is closed exactly once, fixing double-close of OTEL metrics
that yielded warnings. Uses ObjectReleaseTracker.
Key changes:
- PluginBag tracks all plugins (V1, V2, and defaults) in allPlugins,
ensuring proper cleanup during replacement and shutdown.
- RequestHandlerBase asserts that initializeMetrics() is called before
handling requests, preventing memory leaks from untracked contexts.
- InfoHandler and SchemaHandler initialize metrics on dynamically-created
sub-handlers, registering them for cleanup.
- SolrFieldCacheBean: fix recursive close; removed from core metrics.
- HighlightComponent: fix unclosed context due to improper
default/aliasing in SolrCore.loadSearchComponents.
- CoreContainer.shutdown: shut down coreZkRegister executor early so
in-progress async reloads (triggered by ZK config watchers) complete
before cores are closed.
- ObjectReleaseTracker: add a way to inspect contents. Sadly one test
needs to ignore certain unclosed contexts: MissingSegmentRecoveryTest
