Jean-Philippe CLEMENT commented on KARAF-2830:
----------------------------------------------
The problem is the first egrep to match against ‘”([0-9]. [0-9]\..* [0-9])”’.
In fact java version might be followed by a suffix like -ea.
The correct pattern should include this by adding .* which gives: ‘”([0-9].
[0-9]\..* [0-9]).*”’
> Karaf scripts java version check should be more "flexible"
