MissingMethodException with the wrapper class $CLV_safeEval [Grails]

[mauruch]

Hi!

When we try to migrate from code-coverage to open-clover some tests start to fail.

The exception occurs when this code is executed:

I sent an email to support@ and @marek Parfianowicz answered me:

The $CLV_safeEval_grails_utils_Holder() is a helper method generated by OpenClover and added to the class. It is a wrapper for safe-eval operator- '?.'

According to the exception stack trace, the safeEval method takes two arguments:
(grails.utils.Holder, java.lang.Integer)

and the arguments passed to this method are:
(java.lang.Class, java.lang.Integer)

I suspect this is due to the fact that your declaration:
Holders?.config?.locale

refers to the Holders class (type java.lang.Class) and not a Holders instance (type grails.utils.Holders).

I followed the workaround suggested by Marek and it worked perfect:
public static ConfigObject config = Holders.getConfig()
