The reason is that upon the start of the new JVM it loads the default system-wide policy file and the default user policy file which is the Root.policy we just copied. With the testng framework, there is no way to load the custom user policy file without reinstalling the security manager in the test, that said, it doesn't match what the manual test does.

Discussed with Mahendra offline, testng framework `@BeforeTest` performs test setup in the client JVM before test starts in the other JVM. We can use testng framework in this case to handle the policy file operations.
