NullPointerException in PredatorPreBuildAction

[Sam Tannous]

We got the error below when running a build with the predator plugin. "Remove old stable artifacts from the Maven local repository until a certain amount of disk space is freed." was NOT checked. Checking it revealed the values of 'min age' and 'free disk space' were '0.0'. Removing those value, unchecking the option and saving the configuration fixed the problem.

Oops, there's supposedly a 0f default value, I'll see later why it's not being picked up.

I cannot reproduce this locally with a local agent. No matter which data version I try sigh

We had this exact issue with Bamboo 5.11.4.1 build 51120. while this plugin was disabled!
