Details:

The following sequence of statements illustrates a bug in Calendar:

DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss:SSS");
Calendar cal = Calendar.getInstance();
cal.set(2005, 4, 25, 20, 50, 30);
cal.set(Calendar.MILLISECOND, 333);
Date date = cal.getTime();
Calendar ccal = Calendar.getInstance();
ccal.setTime(new Date(date.getTime()));
System.out.println(df.format(ccal.getTime()));
ccal.set(Calendar.MONTH, 0);
System.out.println(df.format(ccal.getTime()));

The output is:

2005-05-25 20:50:30:333
1970-01-01 00:00:00:000

But should be:

2005-05-25 20:50:30:333
2005-01-25 20:50:30:333

Many variations of the above work.  I encountered this from a failing Lucene
JUnit test.  Other that this, Lucene works with GNU Classpath.  However, the
above breaks Lucene's DateTools, which are routinely used for time-tagging
indexed documents.
