RFR: JDK-8312078 : [PPC] JcmdScale.java Failing on AIX

[Deepa Kumari]

On AIX, NMT/JcmdScale.java fails with: java.lang.RuntimeException: 'Incorrect scale value: (null)' missing from stdout/stderr.

Upon analysis the test on Linux and AIX, When a null pointer is passed to the **%s** format specifier, Linux's printf implementation interprets it as an empty string, resulting in the output **(null)**. However, on AIX , the implementation does not interpret it as an empty string. It may handle the null pointer differently, potentially by ignoring it and producing no output at all.
