This rule fails with PATTERN_DSL
rule R when
accumulate (
$p : Person(), $result : sum( MyUtil.add($p.getAge(), 10) ) )
then
insert($result);
end
It generates a lambda with duplicated parameters "_this" and "$p" which are the same Pattern input bind variable.
org.drools.model.Rule rule = D.rule("R").build(D.accumulate(D.pattern(var_$p).bind(var_C6D512FA5D3AACA24A83BF1EE132C0B2,
var_$p,
(_this, $p) -> MyUtil.add($p.getAge(),10)),
So fails at runtime
