I found out this annoying exception after migration from jdk1.6 to jdk1.8. For 1.6 it works fine, but 1.8 returns null:
import org.joda.time.DateTime;
import org.joda.time.DateTimeZone;
import org.joda.time.format.DateTimeFormat;
import org.joda.time.format.DateTimeFormatter;
import org.junit.Test;
public class JodaTest {
public static final String strDate = "Nov 2 2010 12:27AM";
private static final String ISSUED_DATE_PATTERN = "MMM dd yyyy hh:mmaa";
private static final DateTimeZone TIMEZONE = DateTimeZone.forID("America/Chicago");
private static DateTimeFormatter dateTimeFormatter = DateTimeFormat.forPattern(ISSUED_DATE_PATTERN).withZone(TIMEZONE);
@Test
public void testName() throws Exception {
DateTime dateTime = dateTimeFormatter.parseDateTime(strDate); //Exception - Invalid format
System.out.println(dateTime);
}
}
output:
java.lang.IllegalArgumentException: Invalid format: "Nov 2 2010 12:27AM"

What other surprises I can expect with DdateTime after migration?
I had to specify locale explicitly
DateTime dateTime = dateTimeFormatter.withLocale(new Locale("en_EN")).parseDateTime(strDate);
otherwise it doesn't work on jdk>=7
