The specification of Thread.enumerate(Thread[]) method says that

"This method simply calls the enumerate method of this
    thread's thread group with the array argument. "

However, jdk12M does not call to neither java.lang.ThreadGroup.enumerate(Thread[]),
nor java.lang.ThreadGroup.enumerate(Thread[], boolean).

// test is derived from javasoft.sqe.tests.api.java.lang.Thread.enumerate0102

import java.io.PrintStream;

class enumerate0102g extends ThreadGroup {
  int invCount=0;

  public int enumerate(Thread[] tarray) {
invCount++;
return super.enumerate(tarray);
  }

  public int enumerate(Thread[] tarray, boolean recurse) {
invCount++;
return super.enumerate(tarray,recurse);
  }

  enumerate0102g() {
super("enumerate0102g ");
  }

} // end class enumerate0102g



public class enumerate0102 {

  public static void main(String args[]) {
enumerate0102g group=new enumerate0102g();
Thread thrd =new Thread(group, "enumerate0102t");
thrd.enumerate(new Thread[10]);
System.out.println("invCount="+group.invCount);
  }

}




Running the test:
novo37% javac enumerate0102.java
novo37% setenv CLASSPATH .
novo37% java enumerate0102
invCount=0
