Paul King closed GROOVY-8069.
-----------------------------
> Annotation based logging of complex expression in closure throws
> GroovyCastException when statically compiled
> -------------------------------------------------------------------------------------------------------------
>
> Key: GROOVY-8069
> URL: https://issues.apache.org/jira/browse/GROOVY-8069
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> Affects Versions: 2.4.8
> Reporter: Shil Sinha
> Assignee: Shil Sinha
> Fix For: 2.4.9
>
>
> Example:
> {code}
> @groovy.util.logging.Log
> @groovy.transform.CompileStatic
> class Foo {
> void bar() {
> def callable = {
> log.info('a' + 1)
> }
> callable.call()
> }
> }
> new Foo().bar()
> {code}
> The log statement in the code above results in the following runtime
> exception:
> {code}
> org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast
> object 'Foo@14ec4505' with class 'Foo' to class 'java.util.logging.Logger'
> {code}
> The case where the closure is in a static method is similar; the object being
> cast to a Logger is a Class instead.
> This appears to be due to the implicitThis field being set incorrectly on the
> guard method call expression (log.isLoggable(Level) in the default case)
> created in implementations of LoggingStrategy.wrapLoggingMethodCall.
>
> Prior to Groovy 2.4.8, log statements inside closures were not guarded
> (https://issues.apache.org/jira/browse/GROOVY-6932), so this bug wasn't
> visible.
