RFR (S): 6461635: [TESTBUG] BasicTests.sh test fails intermittently

Each test requires 2 files, the actual test code and a helper file.

The helper file will launch a separate java process (called Application), and then start the actual test. The actual test will then attach to the Application.

For example:
PermissionTests.sh: Helper file that will launch Application instance and then start PermissionTest.java
PermissionTest.java: The actual test code that attaches to the Application.

It is the PermissionTests.sh that is started by jtreg (contains the "@test"-tag).

When I port PermissionTest.sh to java I would get 2 files called PermissionTest.java, so some name change is required.

I could have kept the old PermissionTest.java unchanged, but then I would need another name for the prevoius PermissionTest.sh. And I wanted a "clean" Test name for the file containing the "@test"-tag.

I used these names:
TestPermission.java: Helper file.
TestPermissionImpl.java: Actual test code.

I am still new to adding tests for open jdk. I am happy to change the names if they do not follow the naming convention.

Out of curiosity, what is the reason for the rename? I ask because we 
use Basic and similar names in many areas. Also anything in the test 
tree should be a test.
