Subject [jira] [Updated] (GROOVY-8386) Final variable analysis broken with try/catch/finally
Date Sun, 19 Nov 2017 12:26:01 GMT

     [ https://issues.apache.org/jira/browse/GROOVY-8386?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Paul King updated GROOVY-8386:
------------------------------
    Component/s: Compiler

> Final variable analysis broken with try/catch/finally
> -----------------------------------------------------
>
>                 Key: GROOVY-8386
>                 URL: https://issues.apache.org/jira/browse/GROOVY-8386
>             Project: Groovy
>          Issue Type: Bug
>          Components: Compiler
>            Reporter: Paul King
>
> In this code:
> {code}
> final begin
> try {
>   begin = new Date()
> } finally {
>   println 'done'
> }
> {code}
> The current error is:
> {noformat}
> The variable [begin] may be uninitialized
> {noformat}
> But this should only happen if begin is used in the catch or finally blocks or prior
to the first assignment.
> This impacts Spock usage since it converts the following into something similar to above:
> {code}
> @Grab('org.spockframework:spock-core:1.1-groovy-2.4-SNAPSHOT')
> @GrabExclude('org.codehaus.groovy:groovy-all')
> import spock.lang.Specification
> class DummySpec extends Specification {
>     def 'FVA when using Spock'() {
>         given:
>         final begin = new Date()
>         cleanup:
>         println 'done'
>     }
> }
> {code}
