OpenJ9 JDK8 : AIX P10 : Exception in thread "main" java.lang.NoClassDefFoundError: jnurlcldr.shared.findstore.J_Dummy

[Mesbah-Alam]

Following failure is seen in multiple variants of SCURLClassLoaderTests (only JDK 8 specific test) while run on the AIX p10 machine:

Note, the same issue is not reproducible while running on a different, non-p10 AIX machine : https://hyc-runtimes-jenkins.swg-devops.com/view/Test_grinder/job/Grinder/20636.

Somewhat similar older issue: #2653

Assuming this is a test issue until we determine otherwise.

Similar issue seen on JDK 17 too, on the same AIX p10 machine:

Most likely machine issue as these tests work fine on regular AIX machines.
