It should be possible to run this test as a main, without the overhead of building the native image. The use of a Java child greatly reduces the complexity of the test and improves its maintainability. Requiring a native special built program raises the overhead considerably. And all because the VM can't or won't allow its output to be managed. ------------- PR: https://git.openjdk.java.net/jdk/pull/5239
