[jira] [Commented] (GROOVY-8238) multiple-catch statement behaves strangely

["Paul King (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-8238?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16750912#comment-16750912 ] 

Paul King commented on GROOVY-8238:
-----------------------------------

The following example fails in Groovy 2.5.5 but passes in 3.0.0-alpha-4:
{code:java}
import groovy.cli.CliBuilderException
try {
    throw new RuntimeException('not working')
} catch ( RuntimeException | CliBuilderException e ) {
    println e.message
}
{code}
I get the same result on the heads of the two respective branches and with and without {{@CompileStatic}}.

I don't know yet whether the new parser is causing a different path to be traversed during compilation or whether there is a commit/fix we haven't back-ported to the 2_5_X branch as of yet. I'll keep looking.

> This works as expected. But following does not:
> {code:java}
> try {
>     throw new AnyJavaException()
> } catch ( AnyJavaException | AnyGroovyException e ) {
>     println e.message
> }
> {code}
> You get:
> {noformat}
> java.lang.ClassCastException: AnyJavaException cannot be cast to groovy.lang.GroovyObject
> {noformat}
