JBPM-2717 support auto boxing from primivite type to wrapped object class

[rebody]

Hi guys,

I attached a patch for supporting auto boxing from primivite type to wrapped object class.  With it, we could use <true/> for both setCreate(boolean flag) and setCreate(Boolean flag).

Please refer this issue.

any reply will be appreciate.

Done. Enabled  widening primitive conversion in addition to unboxing.
