[10] Review request: JDK-8182564 Create a Debug JDK for Unit Tests

[Chris Bensen]

Kevin, Victor,

Please review this change for unit tests to create a debug JDK. It’s a little odd. It only works in a bash shell because java and javac are copied to java.original and javac.original and replaced with bash scripts which always supply the --upgrade-module-path containing the newly built jdk.packager and jdk.packager.services modules.
