Summary:
can't run rjb-1.3.3 on Mac OS 10.5.8 with JDK1.6.0.26

Detailed description

i've installed on Mac OS Leopard 10.5.8 this update:
JavaForMacOSX10.5Update10.dmg

so now i've got JDK 1.6.0.26 and ruby 1.8.6 

my /System/Library/Frameworks/JavaVM.framework/Versions folder looks like this:
bash-3.2# ls -la
total 80
drwxr-xr-x  16 root  wheel  544 Aug 18 12:26 .

lrwxr-xr-x   1 root  wheel    1 Jul 10 16:38 Current.bak -> A
lrwxr-xr-x   1 root  wheel    3 Aug 18 12:26 CurrentJDK -> 1.6
lrwxr-xr-x   1 root  wheel    3 Jul 10 16:38 CurrentJDK.bak -> 1.5

then i've turned off all other jdks in Java Preferences.

java_home returns this:
bash-3.2# /usr/libexec/java_home 
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

headers are there:
bash-3.2# ls -a `/usr/libexec/java_home`/include
.			JDWP.h			NSJavaConfiguration.h	jawt_md.h		jni_md.h		jvmti.h
..			JDWPCommands.h		NSJavaVirtualMachine.h	jdwpTransport.h		jvmdi.h
AWTCocoaComponent.h	JavaVM.h		jawt.h			jni.h			jvmpi.h

then i've downloaded rjb-1.3.3.zip and ran
bash-3.2# ruby setup.rb config
bash-3.2# ruby setup.rb setup

gem was compiled an i've installed it:
bash-3.2# gem install --local ./rjb-1.3.3-universal-darwin-9.gem 

then i tried running tests and all of them failed with "Can't create JavaVM":
bash-3.2# ruby test.rb
start RJB(1.3.3) test

Shatratos, 
Thnaks for your detailed report.

I close this issue for the workaround. JRuby is nice with the
term of no dll hell.

Arton, hello again.

i've found a workaround for installing buildr. (using JRuby
instead of built-in mac os ruby)
so now i don't need rjb to run it.

if you're still interested in finding this bug (or maybe
it's not a bug) i can run other tests on my machine.

i've recompiled rjb once again with only jdk 1.6 turned on.

ruby -d -w test.rb
fails with JavaVM: Failed to load JVM:
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/
bundle/Libraries/libserver.dylib
JavaVM FATAL: Failed to load the jvm library.

it looks like rjb used JDK 1.5 instead of 1.6.
i've turned off Java 1.5 in /Applications/Utilities/Java
Prefernces - now rjb tests again fail with 
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/
bundle/Libraries/libserver.dylib
JavaVM FATAL: Failed to load the jvm library.

now i'll recompile rjb from sources once again without jdk
1.5 to get clean picture.

Arton, hi!

actually i forgot to set LD_LIBRARY_PATH variable before
testing. so i did this:
export LD_LIBRARY_PATH=`/usr/libexec/java_home`/../Libraries
bash-3.2# echo $LD_LIBRARY_PATH

Hi,

It seems rjb correctly pointed JVM. So I'd like to know what
was happened exactly.
Would you please post the output of * ruby -d -w test.rb ".
And how to create rjb gem ? setup.rb didn't emit gem but rake
-f rjb.rake, did you run rake ?
