Changelog

Datasource & Connection Pool

A major focus of this release was overhauling the datasource connection pool behaviour, fixing several critical bugs that could cause connection leaks, deadlocks, and thread starvation.

  • LDEV-5962 - Connection pool config defaults cause connectionLimit to be ignored, causing threads to block indefinitely
  • LDEV-5963 - idleTimeout and connectionTimeout were ignored due to the pool evictor being disabled
  • LDEV-5964 - Session datasource connections could deadlock
  • LDEV-5965 - Datasource connection validation exceptions should reject the connection rather than silently reuse it
  • LDEV-5966 - Request timeout could leave phantom connections in the pool
  • LDEV-5991 - Datasource idleTimeout default of 1 minute was too aggressive, causing unnecessary connection churn
  • LDEV-6051 - Default maxIdle to connectionLimit for better connection reuse
  • LDEV-6057 - NullPointerException when a datasource defined in CFConfig.json is missing host or port
  • LDEV-6066 - Streamlined verifyDatasource internals

MSSQL

  • LDEV-5970 - MSSQL JDBC 13.2.1 throws “result set is closed” when using lucee.datasource.mssql.modern=true
  • LDEV-5972 - Fix MSSQL Modern Mode properly

Session Management

  • LDEV-6046 - sessionInvalidate() failed to deactivate the old session when using database session storage
  • LDEV-6026 - Added system property lucee.session.scope.complex.warn to control the session scope complex values warning logging (also in 6.2.4.24)

Cache

  • LDEV-6020 - cachedWithinFlush() returned false with struct arguments on multi-argument functions
  • LDEV-6021 - cacheGetDefaultCacheName() did not recognise application-level default caches

Admin & Extensions

  • LDEV-6065 - Admin should not allow null support to be overridden via Application.cfc
  • LDEV-6067 - Added admin update notification test
  • LDEV-6068 - Refactored admin update version handling
  • LDEV-6069 - Extension update check incorrectly reported a downgrade as an upgrade due to inconsistent version padding
  • LDEV-6073 - Page /lucee/formtag-form.cfm missing with form extension since Lucee 6.2.4 (form tag regression)
  • LDEV-6120 - Added support for jakarta-tag-class and javax-tag-class in TLD files, allowing a single extension to target both Lucee 6 (javax) and Lucee 7 (jakarta) servlet APIs

Bug Fixes

  • LDEV-5903 - Repeated class loading issues causing memory leaks in Lucee 6
  • LDEV-6043 - DecimalFormat returned wrong values for numbers >= 10,000,000 due to silent scientific notation conversion
  • LDEV-6048 - Lucee loader version checks had inverted logic and confusing error messages
  • LDEV-6063 - cfflush forced Connection: close, breaking HTTP keep-alive
  • LDEV-6097 - StackOverflowError when duplicating a CatchBlock with a cause chain
  • LDEV-5976 - Error merging cfconfig.json
  • LDEV-6056 - Fix regression: invalid PageSource equals check and mapping comparison causing incorrect page resolution
  • LDEV-6072 - PageSourceImpl missing hashCode() override causing incorrect equality checks

Extensions Bundled

Upgrading

This is a drop-in upgrade for Lucee 6.2.x. Download from https://download.lucee.org/

If you are running a datasource-heavy application, review your connection pool settings after upgrading — several defaults have been corrected and you may want to tune idleTimeout, connectionLimit, and maxIdle explicitly.
