JavaShell DSL native compilation fails on GraalVM 22.2

[essobedo]

If we try to launch the integration test of the JavaShell DSL against the docker image quay.io/quarkus/ubi-quarkus-mandrel:22.2.0.0-Final-java11, it fails with the next error:

Error: Cannot find org.apache.camel.dsl.jsh.JshRoutesBuilderLoader.loadRoutesBuilder, org.apache.camel.dsl.jsh.JshRoutesBuilderLoader can not be loaded, due to jdk/jshell/execution/LoaderDelegate not being available in the classpath. Are you missing a dependency in your classpath?

@essobedo is this mandrel:22.2specific? I wonder whether the same issue occurs with the newest 22.3.1 ?

[essobedo]

@ppalaga Good question, I've just tried with the latest tag and it compiles with success but starting from Mandrel 22.3 only Java 17 is supported so before closing it I need to know first if it is doable to upgrade the root docker image of Camel-K.

[essobedo]

After a deeper investigation, it appears that it is not mandrel related as the bug can also be reproduced on GraalVM 22.2

[essobedo]

Since Mandrel cannot be upgraded in Camel-K for now because of the lack of Java 11 support of Mandrel 22.3, I will propose a workaround of the same type as what have been done for #3617

JSH-DSL will be marked as deprecated in Camel 4.6.0 / CQ 3.11.0. So there's not much value in investing time here IMO.
