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

             Summary: Variable [XXX] is declared final but is reassigned false positive error
                 Key: GROOVY-8571
                 URL: https://issues.apache.org/jira/browse/GROOVY-8571
             Project: Groovy
          Issue Type: Bug
    Affects Versions: 2.5.0-rc-2
            Reporter: paolo di tommaso


Groovy version 2.5.0-rc-2 may report false positive final variable reassignment compilation errors. 

For example: 

{code}
MailerTest.groovy: -1: The variable [PORT] is declared final but is reassigned
{code}

The source code is available at [this link|https://github.com/nextflow-io/nextflow/blob/90f8dcc5d413af06a76e8f7b3e37c5616f721024/src/test/groovy/nextflow/mail/MailerTest.groovy#L120]. 

To replicate the issue follow these steps 

{code}
git clone https://github.com/nextflow-io/nextflow.git
cd nextflow
CI_GROOVY_VERSION=2.5.0-rc-2 make clean compile test
{code} 

Curiously, the CI server build is [reporting a slight version of the same issue|http://ci.groovy-lang.org/viewLog.html?buildId=49488&tab=buildResultsDiv&buildTypeId=JointBuilds_Nextflow_Groovy25xJointBuild#] including sometimes the correct line number instead of -1.
