Maven Plugin for 4.5 mishandling spaces and curly brackets

Hello,

The 4.5 beta fixes some problems handling curly brackets in JSON which is great but it breaks the maven plug-in. Actually this has been reported elsewhere in the forum as occurring back in 4.0.1:
viewtopic.php?f=2&t=12077&p=30395&hilit=spaces#p30395
It occurs on spaces for me and also for curly brackets returning
