RFR: JDK-8158066: SourceDebugExtensionTest fails to rename file

[gary.adams at oracle.com]

After ~1000 testruns I hit a failure in MangleTest and a jtreg agent 
communication
issue with SourceDebugExtension.

https://java.se.oracle.com:10065/mdash/builds/2019-01-10-1159535.gary.adams.jdk-jdb/results?search=status%3Afailed%20AND%20-state%3Ainvalid


*java.io.IOException: tmpFile.renameTo(inOutClassFile) failed*
	at InstallSDE.install(InstallSDE.java:40)
	at MangleTest.testSetUp(MangleTest.java:38)
	at MangleTest.main(MangleTest.java:31)


result: Error. Agent communication error: java.io.IOException:*Agent: unexpected op: 71;*  check console log for any additional details

I added some additional print outs for the rename issue and have run 
~2000 additional
testruns with no test failures repeated, yet. But there were 2 mach5 
reported errors:

    TimeoutException in CLEANUP.


I'll do some more investigation with making the rename operation more robust
before removing SourceDebugExtensionTest from the problem list.
