Updated names as jdk_net_0 has the same failures.

[smlambert]

The two testcases are failing with OutOfMemoryError, which could be a limitation of the machines we have on the public Jenkins server. Trying a run on the temurin-compliance Jenkins server to see if same issue occurs (for those with access to that private server, the link is TCGrinder/4238) - passes on jck-skytap-aix72-ppc64-4
Grinder_20240419103418_JDK11_AIX.tap.txt

I will transfer this issue to the infrastructure repository to see if there is a way to ensure we have same capacity / config on the public AIX machines versus the one attached to the TC Jenkins server.
