RFR [XXS] JDK 13 of JDK-8164819: Make javac's toString() on annotation objects consistent with core reflection

[Joe Darcy]

Hello,

In the course of working on the fix for

         JDK-8164819: Make javac's toString() on annotation objects 
consistent with core reflection

which updates the core reflection toString output of annotations, one 
HotSpot test relies on the old format. This RFR is for the needed update 
to the HotSpot test. The rest of the fix has been out for review on 
core-libs and compiler-dev:

The latest webrev

updates test/hotspot/jtreg/runtime/8007320/ConstMethodTest.java to use 
the new format:
