Description Tim Niemueller 2010-10-11 02:35:57 UTC

Description of problem:
If gcc-java is installed, and java-1.6.0-openjdk, but not java-1.6.0-openjdk-devel, josm is started with gcc-java, which is version 1.5. An incompatibility notice pops up and josm cannot be used.

Version-Release number of selected component (if applicable):
java-1.6.0-openjdk-devel-1.6.0.0-42.b18.fc13.x86_64
java-1.6.0-openjdk-1.6.0.0-42.b18.fc13.x86_64
gcc-java-4.4.4-10.fc13.x86_64
josm-0-0.10.3514svn.fc13.noarch

How reproducible:
Always (if the given package configuration is installed)

Steps to Reproduce:
1. Check that alternatives --display javac mentions a 1.5.0 version instead of 1.6.0
2. Run josm
  
Actual results:
Josm gives an error and does not work.

Expected results:
Josm should run.

Additional info:
The given packages are the constellation that caused problems. I didn't do any Java development recently, but Eclipse pulls in gcc-java, but not openjdk-devel, and I think that has caused the problems. After installation of openjdk-devel one must perform "alternatives --auto javac" to finally get josm to work. A workaround could be to depend on openjdk-devel, but that would actually suck. I wonder why the script does not use the /usr/bin/java that has been setup by the alternatives system, but rather sources a script which chooses the wrong version from the many installed.

Comment 1 Cédric OLIVIER 2010-10-14 20:29:06 UTC

Thanks for reporting this bug. 

Josm launcher is according Fedora guides lines. It is based on this example : http://fedoraproject.org/wiki/Packaging:Java#Wrapper_Scripts

I think problem come from java-functions provided by jpackage-utils.

Awaiting that it's corrected, I can add openjdk-devel dependencies.

Comment 2 Guido Grazioli 2010-11-19 18:41:59 UTC

Cedric, just try to add:

_prefer_jre=1

after the shebang in your wrapper script; as nobody can have a newer jdk without a jre (-devel requires plain package), that should do the trick
