Hi folks!
I know, the subject doesn't look like an Xcode issue, but for me
it is. I blindly went ahead and upgraded my java to 1.5 and now am
having issues with my WebObjects development (actually, I found a
printing bug in Java 5 that's a show stopper for me). So now I want to
set up my WO project to continue using 1.4 instead of 1.5 (besides,
I've just heard that Java 5 isn't supported in WO 5.3).
Sounds easy, right? Lots of documentation about this and plenty
of discussions on the lists talking about how to do this. But none of
it seems to work for me. A sample of the things I've tried:
- setting "target version" AND "source version" to 1.4 in the
"Java Compiler Settings" under "Settings -> Simple View" for each
target in my project (probably only needed the project-named target,
but when that didn't work I did the same in my "Application Server" and
then in the "Web Server" targets as well, in case they made a
difference but they haven't). When those failed, I also added "-target
1.4 -source 1.4" in the "Other Java Compiler Flags" field (without
changing the "target version" and "source version" settings I
previously made), but again with no luck.
- setting "target VM version" to "1.4*" in the "Pure Java
Specific" settings under "Info.plist Entries -> Simple View", again
for each target when the project-named target didn't work. Still no
love.
At this point, nothing has changed - my WO project still claims
to be running in Java 5 (spit out in debug logging) and my simple print
routine still crashes (java crash reported - rdar://4543288). I did
notice something on the java-dev list about the bootclasspath being
needed for this to work, so I tried this next:
- added the following line to the executable itself through "Get
Info" as "Arguments to be passed on launch":
-Xbootclasspath:"/System/Library/Frameworks/JavaVM.framework/Versions/1.4.2/Classes/classes.jar"
Adding this causes something different to happen alright, but
it's not any better ...

Cute (I checked because I'm paranoid - I'm not calling anything
that looks like nanoTime() anywhere in my code:). OK, before I restore
this machine to the point before doing that last OS and Java update
(and possibly report a Xcode bug?), can anyone see what I've been
missing? Each attempt is preceeded with a rather paranoid sequence of
cleaning all targets, deleting the build folder, quitting Xcode,
restarting it and double-checking that all changes stuck - all I can do
is make it crash when printing or crash when the program is starting.
It should be noted that this code ran great before installing Java 5
....

I was told today that if you play a Windows
98 CD backwards, it plays satanic messages. But I reckon that's nothing,
if you play it forward it installs Windows!
