(tz) java 5.0_08 unable to parse 1930's DST days,throwing java.text.ParseException: Unparseable date

    XMLWordPrintable

    Details

      Description

      JAVA 5 update 8(and update 6& 10) failed to parse DST days when -Duser.timezone=America/Montreal is used . These DST days are
      in the 1930's:
         4/28/1935, 4/26/1936, 4/25/1937

      If -Duser.timezone=America/Montreal is not used the DST days are parsed correctly. The day
      immediately before and after the DST day are parsed correctly.

      JDK 1.3.1_18 and 1.4.2_12 do not have the problem.

      The following timezone do not have the problem:
      -Duser.timezone=Africa/Abidjan
      -Duser.timezone=AMERICA/ALASKA
      -Duser.timezone=AMERICA/LOS_ANGELES
