java.lang.RuntimeException: java.nio.file.DirectoryNotEmptyException

While executing Neo4j -3.1.0 testcases on Red Hat Enterprise Linux operating system, using OpenJDK 1.8.0_121 I am facing below error.

       java.lang.RuntimeException: java.nio.file.DirectoryNotEmptyException:test-data/org.neo4j.test.ha.ClusterTest/D4FA83E7CD83F51509461D8F437E0481/testConflictingHaPorts

Looks like it is unable to delete the directory and hence facing the above execption. The user has all the permissions granted. I have checked for hidden files which might cause the issue, however that's not the case .

Below is the java version i am using.

openjdk version "1.8.0_121"
OpenJDK Runtime Environment (build 1.8.0_121-b13)
OpenJDK 64-Bit Zero VM (build 25.121-b13, interpreted mode)

I suspect that the below code snippet is causing the error.

 private void complete( boolean success )
    {
        if ( success && testDirectory != null && !keepDirectoryAfterSuccessfulTest )
        {
            try
            {
                fileSystem.deleteRecursively( testDirectory );
            }
            catch ( MaybeWindowsMemoryMappedFileReleaseProblem fme )
            {
                System.err.println( "Failed to delete test directory, " +
                                    "maybe due to Windows memory-mapped file problem: " + fme.getMessage() );
            }
            catch ( IOException e )
            {
                throw new RuntimeException( e );
           }
        }
        testDirectory = null;
}

Failing and flaky tests come and go all the time. Since issue is quite old, and that test look like it has since been removed, I'll assume it's not relevant any more.
