       Linux and Windows 64Bit with Java 11.0.19 Corretto and Adoptium


      A DESCRIPTION OF THE PROBLEM :
      Core Dump when using GregorianCalen


      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Using the class below on my machine results in a crashed JVM in ~90% of cases.
      When starting with lenient=false it always crashed (~12 tries)

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Should not crash
      ACTUAL -
      crashes

      ---------- BEGIN SOURCE ----------
      import java.util.Calendar;
      import java.util.Date;
      import java.util.stream.IntStream;

      public class Datetest
      {
        public static void main( String[] args )

        {

      Datetest.crashMe(false);
      Datetest.crashMe(true);

        }

        public static void crashMe(boolean crash) {
      IntStream.range( 0, 8000 ).forEach( i -> {

      Calendar timespan = Calendar.getInstance();
      timespan = removeTime( new Date(), crash );
      timespan.getTime();

      if (i%10==0) {
      System.out.println( "Crash: "+crash+ " Iteration: " + i + " / " + timespan.toString() );
      }

      } );

        }
       

        public static Calendar removeTime( Date date, boolean crash_me )
        {

          Calendar calendar = Calendar.getInstance();
          if (crash_me) {
           calendar.setLenient( false );
          }
          calendar.setTime( date );
          calendar = Datetest.removeTime( calendar );
          return calendar;

        }


        public static Calendar removeTime( Calendar calendar )

        {

          calendar.set( Calendar.HOUR_OF_DAY, 0 );

          calendar.set( Calendar.MINUTE, 0 );

          calendar.set( Calendar.SECOND, 0 );

          calendar.set( Calendar.MILLISECOND, 0 );

          return calendar;

        }

       

      }
      ---------- END SOURCE ----------

      CUSTOMER SUBMITTED WORKAROUND :
      Never crashes with lenient=true
      I could also not reproduce this with 32bit-Build (5 tries)

      FREQUENCY : often
