JDK 11 test test/hotspot/jtreg/sanity/MismatchedWhiteBox/WhiteBox.java fails after fix to JDK-8199290.

The test starts failing because  test/lib/ClassFileInstaller.java expects sun.hotspot.WhiteBox$WhiteBoxPermission to be present, but test/hotspot/jtreg/sanity/MismatchedWhiteBox/WhiteBox.java has no inner classes.

LOG:

java.lang.RuntimeException: Failed to find sun/hotspot/WhiteBox$WhiteBoxPermission.class
