As a continuation of the warnings cleanup of JEP 212 (JDK-8042878), the 
new-in-9 lint category of "removal" warnings for use of deprecated for 
removal items should be enable as a fatal warning in the build.

I have out for review under various subtasks the code changes needed to 
suppress the removal warnings (JDK-8177682, JDK-8177683, JDK-8177684, etc.).

Assuming those changes are in, please review the patch needed to enable 
the warning in the build:

  # If warnings needs to be non-fatal for testing purposes use a command 
  # make JAVAC_WARNINGS="-Xlint:all -Xmaxwarns 10000"
-JAVAC_WARNINGS := -Xlint:all,-removal -Werror
+JAVAC_WARNINGS := -Xlint:all -Werror

  # The BOOT_JAVAC setup uses the boot jdk compiler to compile the tools
  # and the interim javac, to be run by the boot jdk.

I'd prefer to get this bug and its subtasks addressed in JDK 9; however, 
if that is not approved as part of rampdown 2, I'll push the associated 
changes to JDK 10 instead.
