Looks good to me.

Minor comment on the test:

   29  * @modules java.base/jdk.internal.org.objectweb.asm
   30  *          java.base/jdk.internal.misc
   31  *          java.management

I thought the test library dependency to java.management was removed at 
one point.
You can verify this by adding a vm option `--limit-modules java.base`.

   32  * @compile -XDignore.symbol.file LargeClassTest.java

This can be simplified to #build LargeClassTest since -XDignore.symbol.file
is not needed.
