Is there a reasonable solution for this yet? I'm running java
1.5.0_06, which sun claims is compatible with the new daylight saving
time change, but it is not. How can I get this fixed? I'm on OS X
10.4.8.

I found two problems. One was my bad and the other was a bug, I
think, that has been hanging around NSTimeZone for quite a while. I
am much less able to find existing bug reports these days.
The first problem is that there are files in the /usr/share/
zoneinfo file that do not represent time zones. They needed to be
filtered out of the zip task.
The second problem is that if one goes through the list of
available IDs for available time zones, some of the them fail. I
was calling toString() on them and got an NPE. Not good.
The offending time zone IDs are:
Asia/Riyadh87
Asia/Riyadh88
Asia/Riyadh89
Mideast/Riyadh87
Mideast/Riyadh88
Mideast/Riyadh89
The "Asia/Riyadh" time zone works, but none of these other do. I
think this is an existing bug, though. I just sounds too familiar.
It turns out the solution to both problems is to filter this stuff
out of the zip file.
So, I am updating the project I posted. The fixFoundation target,
with the excludes on the zip task, will now look like this:
<target name="fixFoundation">
<tempfile property="temp" />
<mkdir dir="${temp}" />
<unjar src="${jarfile}" dest="${temp}" />
<delete quiet="true" file="${temp}/com/webobjects/
foundation/TimeZoneInfo/zoneinfo.zip" />
<zip destfile="${temp}/com/webobjects/foundation/
TimeZoneInfo/zoneinfo.zip" basedir="${zoneInfoDir}"
excludes="*.tab,**/Riyadh87,**/Riyadh88,**/Riyadh89,**/\+VERSION" />
<move file="${jarfile}" tofile="${jarfile}_bak" />
<jar basedir="${temp}" destfile="${jarfile}" />
<delete quiet="true" dir="${temp}" />
</target>
And while we are in the neighborhood, I found out that people may
have more copies of the zoneinfo.zip file hanging about.
I am working with a clean install. If you have an upgraded install,
you may have copies of the file that are not being used, but have
not been removed.
Here is my original list:
/System/Library/Frameworks/JavaFoundation.framework/Resources/Java/
javafoundation.jar
/Library/WebObjects/lib/JavaFoundation.jar (2 copies, one for
WebServerResources and one for Resources)
/Library/WebServer/Documents/WebObjects/Java/com/webobjects/
foundation/TimeZoneInfo/zoneinfo.zip (not in a jar file, actually)
/Library/WebServer/Documents/WebObjects/Java/wojavaclient.jar
Here is an expanded list:
/System/Library/Frameworks/JavaFoundation.framework/Resources/Java/
javafoundation.jar
/System/Library/Frameworks/JavaFoundation.framework/
WebServerResources/Java/JavaFoundation.jar
/System/Library/Frameworks/JavaFoundation.framework/
WebServerResources/Java/com/webobjects/foundation/TimeZoneInfo/
zoneinfo.zip
/System/Library/Frameworks/JavaEODistribution.framework/Versions/A/
WebServerResources/Java/wojavaclient.jar
/System/Library/WebObjects/WODocumentRoot/WebObjects/Java/
JavaFoundation.jar
/System/Library/WebObjects/WODocumentRoot/WebObjects/Java/
wojavaclient.jar
/System/Library/WebObjects/WODocumentRoot/WebObjects/Java/com/
webobjects/foundation/TimeZoneInfo/zoneinfo.zip
/System/Library/Java/wojavaclient.jar
/Library/WebObjects/lib/JavaFoundation.jar
/Library/WebServer/Documents/WebObjects/Java/JavaFoundation.jar
/Library/WebServer/Documents/WebObjects/Java/wojavaclient.jar
/Library/WebServer/Documents/WebObjects/Java/com/webobjects/
foundation/TimeZoneInfo/zoneinfo.zip
Yikes!
