Description

The builder is creating unmodifiable map here.
'createExpression' call uses computeIfAbsent here, which then fails with java.lang.UnsupportedOperationException.

Problem can be simulated on Camel-quarkus integration-tests/csimple. Failure can be seen in this PR - https://github.com/apache/camel-quarkus/pull/5747
