I am aware of the following potential implementations:

Implementation 1
{code}
    // Thread stack trace
   StackTraceElement[] trace = Thread.currentThread().getStackTrace();
{code}

Implementation 2
{code}
  // use SecurityManager
    private static final class ClassContextSecurityManager extends SecurityManager {
        protected Class<?>[] getClassContext() {
            return super.getClassContext();
        }
    }
    private static ClassContextSecurityManager getSecurityManager() {
        try {
            return new ClassContextSecurityManager();
        } catch (java.lang.SecurityException sm) {
            return null;
        }
    }

  ClassContextSecurityManager securityManager = getSecurityManager();
  Class<?>[] trace = securityManager.getClassContext();
{code}

Implementation 3
{code}
    // StackWalker API (new in Java9)
    StackWalker WALKER = StackWalker.getInstance();
    List<StackFrame> frames = WALKER.walk(s -> s.limit(4).collect(Collectors.toList()));
{code}
