java.util.GregorianCalendar.computeTime() does not throw IllegalArgumentException
when lenient is set to false and some fields have been set to illegal value.
The list of fields the method fails with is: WEEK_OF_YEAR, WEEK_OF_MONTH, DAY_OF_YEAR, 
DAY_OF_WEEK_IN_MONTH.

Javadoc says about GregorianCalendar.computeTime:
    
     Converts time field values to UTC as milliseconds.
     exception: IllegalArgumentException if any fields are invalid.
     
Javadoc says about Calendar.setLenient:

     Specify whether or not date/time interpretation is to be lenient.  With
     lenient interpretation, a date such as "February 942, 1996" will be
     treated as being equivalent to the 941st day after February 1, 1996.
     With strict interpretation, such dates will cause an exception to be
     thrown.

Here is the test demonstrating the bug:

-----------------Test.java------------------------
import java.util.*;

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


    boolean passed = true;
    GregorianCalendarTest calendar = new GregorianCalendarTest();
    calendar.setLenient(false);
    Date date = (new GregorianCalendar(1996,0,3)).getTime();
    for (int field = 0; field < Calendar.FIELD_COUNT; field++) {
      calendar.setTime(date);
      int max = calendar.getActualMaximum(field);
      int value = max+1;
      calendar.set(field, value); 
      try {
          calendar.computeTime(); // call method under test
          System.out.println("Test failed with field " + fieldName[field]);  
          System.out.println("  date before:  " + date);
          System.out.println("  date after:   " + calendar.getTime());
          System.out.println("  value: " + value + "  (max = " + max +")");
          passed = false;
       } catch (IllegalArgumentException e) {
       } 
     }

    if (passed)  System.out.println("Test passed");
  }

  static final String[] fieldName = {
          "ERA", 
          "YEAR", 
          "MONTH", 
          "WEEK_OF_YEAR", 
          "WEEK_OF_MONTH", 
          "DAY_OF_MONTH", 
          "DAY_OF_YEAR", 
          "DAY_OF_WEEK", 
          "DAY_OF_WEEK_IN_MONTH", 
          "AM_PM", 
          "HOUR", 
          "HOUR_OF_DAY", 
          "MINUTE", 
          "SECOND", 
          "MILLISECOND", 
          "ZONE_OFFSET", 
          "DST_OFFSET"
  };


} 

class GregorianCalendarTest extends GregorianCalendar { 
         // access to protected method

    public GregorianCalendarTest(int year, int month, int day) {
      super(year, month, day);
    }
    public GregorianCalendarTest() {
      super();
    }
    public void computeTime() {
       super.computeTime();
    }

}
