Description Cédric OLIVIER 2010-10-11 20:13:53 UTC

Description of problem:

I have followed guidelines to made a wrapper script to launch josm.jar : http://fedoraproject.org/wiki/Packaging:Java#Wrapper_Scripts

If there isn't any java-1.6.0-openjdk-devel installed but java-1.5.0-gcj-devel and java-1.6.0-openjdk

The wrapper select an 1.5 java version. 

alternatives --display java is java 1.6, I am expecting that the wrapper select java 1.6

Version-Release number of selected component (if applicable):
josm-0-0.11.3592svn.fc13.noarch (problem with wrapper)
java-1.5.0-gcj
java-1.5.0-gcj-devel
java-1.6.0-openjdk

don't install java-1.6.0-openjdk-devel

How reproducible:
Try to launch josm it fail because java 1.5 is used and josm requires java 1.6 as it specified in rpm spec file.

Steps to Reproduce:
1.yum install java-1.5.0-gcj-devel
2.yum install ant josm
3.alternatives --display java is set to java 1.6
4.alternatives --display javac is set to javac 1.5
5.Try to run wrapper specified in GuideLines, there is java 1.5 selected.
  
Actual results:

Java 1.5 selected by guidelines wrapper instead of java 1.6

Expected results:
Wrapper lauching same java version as alternatives is configured (java 1.6 in this case)
