Plugin incompatible with Java 21 - ClassNotFoundException: javax.xml.bind.DatatypeConverter

Environment
- TestComplete Jenkins Plugin version: 2.10
- Jenkins version: 2.555.1
- Java version: 21.0.7

The TestComplete plugin throws a ClassNotFoundException for 
javax.xml.bind.DatatypeConverter when running on Java 21. 
This causes all TestComplete jobs to fail.

java.lang.ClassNotFoundException: javax.xml.bind.DatatypeConverter

Caused: java.lang.NoClassDefFoundError: javax/xml/bind/DatatypeConverter

javax.xml.bind (JAXB) was removed in Java 11 via JEP 320. The plugin 
is calling javax.xml.bind.DatatypeConverter in LogNodeUtils.java:425 
which no longer exists in Java 11 and above.

Downgrading Java on the node is not possible as the Jenkins controller 
is running Java 21 (class file version 65.0) and the node must match it
