Since build 447 unable to use nashorn-core

[kangarko]

Background:

There is a problem since Velocity build 447 preventing Rhino (javascript engine) to work. The problem started in build 447 after updating the dependencies: f2d6e14

This affects all plugins using JavaScript variables which are now unable to use the nashorn-core library.

How to fix:

This has already been fixed at Java's team, see openjdk/nashorn@5e78947

However ETA for nashorn-core release, so the relevant library has prepared a patch already:

apache/logging-log4j2#3125

Please consider shipping logging-log4j2 2.25.0-SNAPSHOT into velocity to solve this problem.

Update: This could be solved by bumping the log4j jul dep as mentioned at apache/logging-log4j2#3125 (comment)
