Hello,
Many thanks to those who have tested.
My greatest thanks go to Art Kraymer who correctly pointed out that this
update was *not needed*. The j2sdk that we pushed out in the errata's
last time (j2sdk-1.4.2_12) actually has the correct time zone changes.
How did we/he determine that the time zone change was in there, despite
documentation from Sun saying it wasn't? He tested it.
Here is a Java script that looks at the various time zone stuff, and
determines if you have the proper time zone changes.
http://home.fnal.gov/~kreymer/DSTCheck.java
To test it, compile it, then run it with the various versions of java
you have. As you can see below, if you have different versions, just
use the full path for the version you have.
$ javac DSTCheck.java

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
! YOUR JVM REQUIRES UPDATES FOR NEW DST CHANGES !
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
So, in conclusion, unless someone can dispute this test, and show me
that we really do need to have our java updated, I'm not going to push
out the newest java into the errata areas.
I will leave them in the testing area for now, so if people do want to
update, they can. The instructions are below.
SL3
yum -c
ftp://ftp.scientificlinux.org/linux/scientific/30rolling/testing/yum.conf
update
SL4
yum -c
ftp://ftp.scientificlinux.org/linux/scientific/40rolling/testing/yum.conf
update
or
yum --enablerepo=sl-testing update
Thanks
Troy
