class hello {
    public static void main(String[] args) {
      {
        int var = 5;
        System.out.println("Hello World!" + var); // Display "Hello World!"
      }
      for (int i = 0; i < 100 ; i++) {
          // nuke the anonymous classes
          System.gc();
      }
    }
}

Creates 17 anonymous classes because of the concatenation of var.

Printing in Unsafe_Define_AnonymousClass:
There are 16 different ones of these:
Anonymous class java.lang.invoke.LambdaForm$BMH/249515771 created host class java.lang.invoke.LambdaForm

And one of these, which is added as a dependency to the application class loader:
Anonymous class java.lang.invoke.LambdaForm$MH/586617651 created host class java.lang.invoke.LambdaForm

This seems crazy inefficient. Also need to figure out why the $BMH are never unloaded.
