It first cleans up any temp files matching the prefix and suffix created for this test case.  The test fails because the fix for JDK-8160286 that creates the jmod temp file in the tmp directory and it was updated to use Files.walk that may fail to read the file attributes if the user doesn’t have access.

When this test was added originally jmod was creating the tmp file in 
the current working directory. 

To avoid interference you could run with test with java.io.tmpdir set
to the current working directory, “testng/othervm -Djava.io.tmpdir=. ..."
