MacOS Tiger & java 5.0

1°/ Download the jdk
http://www.apple.com/support/downloads/java2se50release1.html
, and the doc
http://www.apple.com/support/downloads/
java2se50developerdocumentation.html

2°/ Install the 2 packages downloaded above

3°/ To start IDEA with java 5.0:

/Applications/Utilities/Java/J2SE 5.0/Java Preferences
Tab: "general"-"Java Application Runtime Settings"
drag J2SE 5.0 above J2SE 1.4.2

Note: typing "java -version" in the terminal will still return:
java version "1.4.2_07"


4/Compiling java code with J2DE 5.0:

4.1 create a JSDK 5.0:
Create a new JSDK, and point to
/System/Library/Frameworks/JavaVM.framework/Versions/1.5/Home

Note: Due to a a bug, you have to add the 2 doc jars manually:

/System/Library/Frameworks/JavaVM.framework/Versions/1.5/Home/appledocs.jar
/System/Library/Frameworks/JavaVM.framework/Versions/1.5/Home/docs.jar

The bug: http://www.jetbrains.net/jira/browse/IDEA-1718

4.2, the rest is not mac specific:
in "Project Settings"."Path":
"language level for project.. (effective on restart) "
in "Project Settings"."Compiler":
"use generics-eneabled compiler",

5.0 doesn't seem to work with the release version of Idea just the EAP.

I remember the IDEA 4.5 specs mentioned support for Java 1.5

It's a different thing. 4.5 will only run under 1.4 itself but allows development
of 1.5 projects

I remember the IDEA 4.5 specs mentioned support for Java 1.5

So this means, that java developers on OSX should not
upgrade to java 5.0 until IDEA 5.0 comes out?

Not necessarily - It only means that the current release version of Idea doesn't work with Java 1.5 on the Mac.
