after talking to @M-Davies ,It looks like it isn’t using an OpenJ9 boot jdk.

The problem here is that the initial change only sets an openj9 boot jdk on machines that don't have a valid boot jdk installed. The change isn't used for instances where we don't have to download a boot jdk. We would need to alter the inital setting of the boot jdk to cover this weakness too

We've disabled the use of the installed boot JDKs for now in the jenkins machine definitions but should look at re-enabling it later once OpenJ9 have the symbols defined in order to avoid having to have two boot JDKs of each level on the build machines.
