Daniel.Sun closed GROOVY-8005.
------------------------------
Resolution: Fixed
> [parrot] NPE when using try-with-resources with a missing semi-colon
> --------------------------------------------------------------------

> Key: GROOVY-8005
> URL: https://issues.apache.org/jira/browse/GROOVY-8005
> Project: Groovy
> Issue Type: Bug
> Reporter: Guillaume Laforge
> Assignee: Daniel.Sun
>
> When testing the try-with-resouces construct in the Groovy console, I did a
> mistake, and forgot the semi-colon in between resources:
> {code}
> def input = new File('./NOTICE')
> try (
> FileInputStream fin = new FileInputStream(input)
> GZIPOutputStream out = new GZIPOutputStream(new FileOutputStream(output))
> ) {
> byte[] buffer = new byte[4096]
> int nread = 0
> while ((nread = fin.read(buffer)) != -1) {
> out.write(buffer, 0, nread)
> }
> }
> {code}
> And I got the following NPE:
> {code}
> java.lang.NullPointerException
