Looks fine.  The installed providers are our implementation and silently 
ignore any exception would make it really hard to diagnose problems.   
This change will help the diagnosability.

If the default policy is not cached early before any test policy is 
constructed, the test might get the wrong Policy object set by the test 
previously (for example, if it runs in agentvm mode).   It would be more 
reliable if this is cached as the static field in the test class (i.e. 
the enclosing class of the policy subclass) - like CallerSensitiveTest.

test/jdk/sun/util/locale/provider/Bug8038436.java
- I think the test fix should be part of JDK-8189272, right?
