Changes in Oak 2.8.0
--------------------
** Sub-task
* [OAK-12249] - Don't create empty ES indices
** Bug
* [OAK-12341] - Thread Contention
authentication.external.impl.principal.SyncConfigTracker
* [OAK-12344] - ORDER BY: Lucene, Elastic and Oak's query engine
sort missing and invalid values differently
* [OAK-12364] - XPath queries fail to parse when path names
contain invalid XML characters
* [OAK-12365] - [oak-search] FulltextIndexEditor does not delete a
document when a node's last indexed property is removed
* [OAK-12380] - The export-package manifest header of
oak-search-elastic contains a class name.
* [OAK-12396] - Fix countDirectChildren depth
* [OAK-12398] - Move CacheMaintenanceExecutor to an internal
package to avoid split package issue
* [OAK-12400] - Online revision cleanup can delete referenced
segments on a store not written in compaction order (e.g. a promoted
cold standby)
* [OAK-12401] - ISCHILDNODE cost estimation for Lucene/Elastic
property indexes is too high
* [OAK-12404] - CompactionWriter.flush() persists partial writer
before target writer
* [OAK-12408] - Standalone cleanup() never journals gc.log leading
to SNFE on cold standby / backup
* [OAK-12415] - oak-search-elastic: retry per-item bulk update
version conflicts instead of dropping them
* [OAK-12421] - ForkJoinUtilsTest can be flaky
* [OAK-12439] - Restart reconfigured oak-run logging contexts to
stop orphaned scanners
* [OAK-12442] - Isolate the conditional-path query test from
built-in index counters
* [OAK-12444] - Fix reference-retention timing in DataStoreCommandTest
* [OAK-12445] - AzureDataStoreRegistrar ignores staging and minimum
record length settings
* [OAK-12450] - Concurrency and memory-retention issues in
ThreadSpecificSegmentBufferWriterPool
* [OAK-12457] - Oak-run check wrongly reports "No good revision
found" when the corrupt path doesn't exist in older revisions
** Epic
* [OAK-12346] - Oak should compile & test on Java 26
** New Feature
* [OAK-12372] - Lucene indexing fails when a property with more
than 8191 characters is used for facets."
** Improvement
* [OAK-10339] - Migrate to SLF4J 2.x
* [OAK-12100] - Queries with nodeName don't run efficiently
(estimated cost is too high)
* [OAK-12173] - Query traverses even with correct index, at startup
* [OAK-12307] - Indexing a disabled index without async leads to a
sync index
* [OAK-12353] - oak-search-elastic: improve elastic dynamicBoost
persistence

Comparator chain on every call, dominating GC pressure during full

* [OAK-12393] - Update MySql JDBC driver version to
com.mysql:mysql-connector-j:9.3.0 in profile rdb-mysql

for failing/stuck lanes and after restart, hiding stale lanes from alerts
* [OAK-12402] - Add primitive overloads to Validate.checkArgument
* [OAK-12405] - MapEntry.compareTo() allocates a new Comparator
chain on every call, adding GC pressure during segment map writes

* [OAK-12413] - Pre-size predictable ArrayList allocations in the
compaction write path
* [OAK-12414] - Simplify and pre-size list-record bucket
