I created a build specifying jdk 1.5. This failed, so I added a 1.4 jdk to bamboo then changed the build to use 1.4. However the logs show that it continues to use the original 1.5 jdk, even after a restart of the app.

This is backed by the fact that I then removed the 1.5 jdk from bamboo completely, and it still builds using 1.5.

Addition: It seems that it is actually using a different jdk to run the ant script, which was never even specified in the admin screen. This is not even the JAVA_HOME value on the server
