Description

Hello,

during some performances tests, we noticed a difference between camel-xslt 2.24.2 & 3.11.1.

Here is a simplified repo to reproduce: https://github.com/jgreffe/camel-perf-xslt-test

Please execute:

• using JDK8: mvn clean test -Dcamel.test=2.24.2
• using JDK11: mvn clean test -Dcamel.test=3.11.1

We have these results:

[INFO] ********************************************************************************
[INFO] Testing done: testMock(XSLTTest)
[INFO] Took: 0.295 seconds (295 millis)
[INFO] ********************************************************************************
[INFO] Apache Camel 2.24.2 (CamelContext: camel-1) is shutting down

[INFO] ********************************************************************************
[INFO] Apache Camel 3.11.1 (camel-1) shutting down (timeout:10s)

Do you have an idea of root cause?
