Some problem to launch demo in jfrtracer branch.

[gunlee01]

I met the trouble below after run mvn package the project and ./target/bin/xxxService. Did I miss something?

Failed to scan [file:/xxx/problematic-microservices/robotshop-order-service/target/repo/org/glassfish/jaxb/jaxb-jxc/2.4.0-b180725.0644/txw2-2.4.0-b180725.0644.jar] from classloader hierarchy

I typically only get that when running on JDK8. When running on JDK11, using the generated launchers (target/bin/*Service), I don't see that problem. I haven't bothered to check why the problem occurs, but as far as I can tell it doesn't affect the actual running of the micro service. I.e. even if you get that exception, it is only a failure to scan some zip files (for what I assume is annotations), and it will not affect the running of the micro service.

Thank you. Let me check something more.

Hi @gunlee01!

Did you find out a good way to do something about this? Since I am registering stuff explicitly, I think it's probably ok to disable the scanning altogether, however that is done.
