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
