RFR: JDK-8299424: containers/docker/TestMemoryWithCgroupV1.java fails on SLES12 ppc64le when testing Memory and Swap Limit

[Matthias Baesken]

On the old SLES12 ppc64le machine we do not have memory.memsw.limit_in_bytes :
ls -alL /sys/fs/cgroup/memory/memory.memsw.limit_in_bytes
ls: cannot access /sys/fs/cgroup/memory/memory.memsw.limit_in_bytes: No such file or directory

This leads to

[0.163s][trace][os,container] Memory and Swap Limit is: 18446744073709551614
memory_and_swap_limit_in_bytes: not supported

And the check in containers/docker/TestMemoryWithCgroupV1.java fails :

java.lang.RuntimeException: 'Memory and Swap Limit is: 157286400' missing from stdout/stderr
at jdk.test.lib.process.OutputAnalyzer.shouldContain(OutputAnalyzer.java:221)
at TestMemoryWithCgroupV1.testMemoryLimitWithSwappiness(TestMemoryWithCgroupV1.java:88)

at java.base/java.lang.Thread.run(Thread.java:1623)

Probably we should handle this situation and check for "memory_and_swap_limit_in_bytes: not supported" or something similar .
