Regression in executing EL-methods with parameters after upgrading from JBossWeb 7.0.4

I have a commandLink like

<ice:commandLink action="#

{lukkoinfo.lukkoinfoHakija(tilaus.id.tilausnumero)}" immediate="true">x</ice:commandLink>

which worked fine for Beta1 but fails on upstream master. I bisected it down to the place where JBossWeb was upgraded from 7.0.4 to 7.0.5 where it fails.

The stack trace is

15:29:00,986 WARNING [javax.enterprise.resource.webcontainer.jsf.lifecycle] (http--127.0.0.1-8080-1) #{lukkoinfo.lukkoinfoHakija(tilaus.id.tilausnumero)}
