FileSystemConnector behaves strangely on NFS

Some of FileSystemConnector tests are failing on NFS drive.

Several tests are failing
Example
<testcase classname="org.modeshape.connector.filesystem.FileSystemConnectorWritableTest" name="shouldBeAbleToCreateFileWithContent" time="3.818">
<failure type="junit.framework.AssertionFailedError">junit.framework.AssertionFailedError:
at org.modeshape.connector.filesystem.FileSystemConnectorWritableTest.assertContents(FileSystemConnectorWritableTest.java:598)
at org.modeshape.connector.filesystem.FileSystemConnectorWritableTest.shouldBeAbleToCreateFileWithContent(FileSystemConnectorWritableTest.java:135)
</failure>
</testcase>

Moreover an exception is printed to standard error
org.modeshape.graph.connector.RepositorySourceException: Error moving temporary data file to path "/tmp/modeshape5274288099061789508.tmp to /qa/services/hudson/hudson_workspace/workspace/soa-modeshape-single/modeshape/extensions/modeshape-connector-filesystem/target/repositories/test/testFile" in workspace "test" in Test Repository

I have tweaked FileSystemWorkspace source code a little bit and I have found that in method putNode there is a condition
if (!temp.renameTo(parentFile)) {
that is evaluated to true. I have added an information lines to be printed in the condition
System.err.println("UPDATE ERROR " + temp.getCanonicalPath() + " " + parentFile.getCanonicalPath());
System.err.println("UPDATE " + temp.exists());
System.err.println("UPDATE " + parentFile.exists());
System.err.println("UPDATE " + parentFile.getParentFile().exists());

Which gives me result
UPDATE ERROR /tmp/modeshape5274288099061789508.tmp /qa/services/hudson/hudson_workspace/workspace/soa-modeshape-single/modeshape/extensions/modeshape-connector-filesystem/target/repositories/test/testFile
UPDATE true
UPDATE false
UPDATE true

and when I tried to execute 'mv /tmp/modeshape5274288099061789508.tmp /qa/services/hudson/hudson_workspace/workspace/soa-modeshape-single/modeshape/extensions/modeshape-connector-filesystem/target/repositories/test/testFile' then the command was executed successfully.
