Hello,  

In the TestMemoryAwareness.java docker related test the following issue has been observed
on a Linux machine:

java.lang.RuntimeException: 'OperatingSystemMXBean\\.getFreeSwapSpaceSize: [1-9][0-9]+' missing from stdout/stderr
 
               at jdk.test.lib.process.OutputAnalyzer.shouldMatch(OutputAnalyzer.java:306)
               at TestMemoryAwareness.testOperatingSystemMXBeanAwareness(TestMemoryAwareness.java:154)
               at TestMemoryAwareness.main(TestMemoryAwareness.java:65)
               at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
               at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:64)
               at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)
               at java.base/java.lang.reflect.Method.invoke(Method.java:564)
               at com.sun.javatest.regtest.agent.MainWrapper$MainThread.run(MainWrapper.java:127)
               at java.base/java.lang.Thread.run(Thread.java:832)

Jie Fu proposed an adjustment to OperatingSystemImpl getFreeSwapSpaceSize to address this.

    Hmm okay, probably better to open a new one. Jie - should I open a separate JBS issue ? Or do you want to do it ( you proposed the patch for the getFreeSwapSpaceSize  issue) ? 

   
Please feel free to  open a separate JBS issue.
And many thanks for fixing it.

Best regards,
Jie
