Summary

In our daily jobs, we experienced OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000006af400000, 4034920448, 0) failed; error=' Not enough space' (errno=12)#.

It was some improvements with https://github.com/quarkus-qe/quarkus-test-framework/pull/1351 Apart from that, the' HttpAdvancedIT' test also needs to be updated, and I did with this PR. I've tested in our Jenkins-job and the test PASSED.
