Hi,

Lastweek My jenkins went down. I have restarted the service then we logged in to Jenkins it shows many issues related to plugins . Some of the plugins are not loaded properly. For few plugin they are saying downgrade the plugin version. its effected for many plugins

In the log its showing some log4jHopatch details
java.lang.SecurityException: class “Log4jHotPatch”'s signer information does not match signer information of other classes in the same package
at java.base/java.lang.ClassLoader.checkCerts(ClassLoader.java:1151)
at java.base/java.lang.ClassLoader.preDefineClass(ClassLoader.java:906)

Jenkins Version : 2.263.1

Can any please tell me why this is happend

Thanks,
Ramakrsihna

The log4jhotpatch error is Cannot attach `Log4jHotPatch` agent to official releases of Jenkins · Issue #53 · corretto/hotpatch-for-apache-log4j2 · GitHub I think, but it’s probably not the reason for the plugin errors, so you’d better post those in more detail.

Similarly exception for more that 50 plugins

You’ll need to install those plugins. Plugin updates for Docker images are easier to manage if you use the plugin installation manager tool. It will download dependent plugins as needed.
