Bumps ch.qos.logback:logback-classic from 1.3.15 to 1.5.21.

Release notes

Sourced from ch.qos.logback:logback-classic's releases.

Logback 1.5.21

2025-11-10 Release of logback version 1.5.21

• Invocations of turbo filters in isDebugEnabled, isInfoEnabled()... remain as they were, untouched. However, any installed instances of TurboFilter are now invoked also from within the log(LoggingEvent) method of Logger with the contents of the LoggingEvent, typically via the fluent API. This fixes issues/871.

• Removed reentry-guard in most subclasses of UnsynchronizedAppenderBase where it was not needed.

• Initialization procedure has been simplified by removing the step instantiating a SerializedModelConfigurator. However, it is still possible to set up SerializedModelConfigurator as a custom configurator.

• JsonEncoder is now friendlier to derivation by sub-classes as requested in issues/979.

• Fixed XMLLayout thread safety issue reported in LOGBACK-427.

• Removed superfluous buffering in Zip, GZ and XZ compression code.

• A bit-wise identical binary of this version can be reproduced by building from source code at commit fed6f37ffe3449e40f6a9fffe050936a33116bd1 associated with the tag v_1.5.21. Release built using Java "21" 2023-10-17 LTS build 21.0.1.+12-LTS-29 under Linux Debian 11.6.

Logback 1.5.20

2025-10-19 Release of logback version 1.5.20

• Due to potential vulnerabilities associated with dynamic, i.e. runtime, java code compilation and execution (using Janino), the 'condition' attribute within the <if> element is deprecated and will be removed in 2027.

An online migration service is provided to help with the transition.

The <condition> element, new in this version, admits custom PropertyEvaluator as a recommended alternative. See also the updated documentation on conditional configuration.

• Initialization procedure was incorrectly reported as having been simplified in this version, i.e. version 1.5.20 by removing the step instantiating a SerializedModelConfigurator. The actual simplification was done in version 1.5.21

• A bit-wise identical binary of this version can be reproduced by building from source code at commit 930fb15c993a4344bcecc6ba2225c12a2c38e676 associated with the tag v_1.5.20. Release built using Java "21" 2023-10-17 LTS build 21.0.1.+12-LTS-29 under Linux Debian 11.6.

Logback 1.5.19

2025-09-30 Release of logback version 1.5.19

• Disallow "new" operator in the condition attribute of <if> elements. This fixes an ACE vulnerability recorded as CVE-2025-11226.

• At initialization time, slightly better reporting about watched configuration files.

• Softer message regarding usage of ConsoleAppender and its potential impact on performance.

• In ViewStatusMessagesServlet, restrict processing of "Clear" button to POST method. This change was proposed by Ralf Wiebicke who also provided the relevant PR.

• A bit-wise identical binary of this version can be reproduced by building from source code at commit e572d4f87f06674788eb3ca7148e8d1dffc615fa associated with the tag v_1.5.19. Release built using Java "21" 2023-10-17 LTS build 21.0.1.+12-LTS-29 under Linux Debian 11.6.

Logback 1.5.18

2025-03-18 Release of logback version 1.5.18

• Added support for XZ compression for archived log files. Note that XZ compression requires Tukaani project's XZ library for Java. In case XZ compression is requested but the XZ library is missing, then logback will substitute GZ compression as a fallback. This feature was requested in issues/755.

• Removed references to java.security.AccessController class. This class has been deprecated for some time and is slated for removal in future JDK versions.
