java/net/URLClassLoader/closetest/CloseTest.java and GetResourceAsStream.java failed with existing dir

These two tests failed with different but probably related problems. From test logs, both of the failures seem to be due to existing dir "C:\Users\aurora\sandbox\gresults\testoutput\jdk_net\JTwork\classes\java\net\URLClassLoader\closetest\testdir"

This is test output by java/net/URLClassLoader/closetest/CloseTest.java
