RFR JDK-8190315: Test tools/javac/tree/NoPrivateTypesExported.java failing

[Jan Lahoda]

Hi,

test/langtools/tools/javac/tree/NoPrivateTypesExported.java is failing. 
The intent of the test is to verify the API elements don't refer to 
non-public types. This is similar to Xlint:exports, but older. Seems 
reasonable to keep the test for now, despite it might be superseded by 
-Xlint:exports. The issue why the test is failing is that it does not 
ignore constant annotation values, which the proposed fix is doing:
Bug: https://bugs.openjdk.java.net/browse/JDK-8190315

Thanks,
