I fixed this issue on the master and backported the fix to the 5.5.x branch.
Let me know if it should be backported also on the 5.3.x branch where it has been reported.

> Description of problem:
> Given a DSL configuration containing
> > [when]Foo with {var} bars=Foo( bars == {var} )
> and a probably incorrect rule containing
> > when
> >     Foo with {var} bars
> When this rule is expanded by org.drools.lang.dsl.DefaultExpander the expansion gets stuck in an infinite loop, probably substituting {var} with {var} again and again.
