org.modeshape.jcr.AbstractJcrNode.createPatternsFor(String...) does not escape "+"

Short: Method createPatternsFor(String...) in org.modeshape.jcr.AbstractJcrNode does not escape the "+" character.

Full:
There are the nodes:
/folder/node+1
/folder/node+2

The result of calling

folder.getNodes("node+*")

will be an empty iterator because createPatternsFor(String...) does not escape the "+" and the resulting regular expression would be

node+.*

Instead it has to be

node\\+.*
