Description

Groovy compiler seems to be generating calls like {{ new Integer() }} and {{ new Long() }} (also for other number wrapper types), which FindBugs tool calls out as performance issues and suggests that the equivalent calls {{ Integer.valueOf() }} and {{ Long.valueOf() }} be used.

Class generation needs to change a bit to support it to reduce the errors reported by FindBugs for groovy classes.
