-------------------------------------------------------------

When I run this example:
{code}
import groovy.transform.*
import groovy.util.logging.*

@Grab('org.slf4j:slf4j-simple:1.7.21')
@Slf4j
@CompileStatic
class TestException {
    static void main(String[] args) {
        try {
            throw new NullPointerException('ahh!')
        } catch (NullPointerException | IOException e) {
            log.error('error {}', e.message)
        }
    }
}
{code}
I get the same error as you on the GROOVY_2_4_X branch but I get no error and this output on master:
{noformat}
[Thread-3] ERROR TestException - error ahh!
{noformat}
I looked for an issue that might have fixed this (in case it could be easily back-ported) but I haven't found one yet.

Also, worth noting that changing @CompileStatic to @TypeChecked also avoids the CCE on 2.4.6.
