I'm having problems getting Ant 1.4.1 to work with JDK 1.4 beta3.
I get the 'Cannot use classic compiler' error:
[seb@ART002001] 150 # ant compile
Buildfile: build.xml
init:
compile:
[javac] Modern compiler is not available - using
classic compiler
[javac] Compiling 11 source files to H:\dev\java\obj
BUILD FAILED
H:\dev\java\build.xml:14: Cannot use classic compiler, as it is not available A common solution is to set the environment variable JAVA_HOME to your jdk directory.
Total time: 3 seconds
Exit 1
I looked this up in the archives, and it seems other people had this problem, but the solution was always adding tools.jar to the classpath (or setting up JAVA_HOME correctly). I however think these things are fine, and running ant in debug mode seems to confirm this:

(Note the java.class.path). This happens though:

So i don't really understand what's wrong here, unless Ant 1.4.1 has an issue with the Sun 1.4 beta 3 SDK?
Any help would be appreciated!
