-------------------------------------------------------------
Added code tags. Plus here is a JavaShell snippet to confirm the Java behaviour:
{code:groovy}
def js = new org.apache.groovy.util.JavaShell()
js.run('Main', '''
public class Main {
public static void main(String[] args) {
final int i;
final boolean a = true;
if (a) {
i = 1;
} else {
throw new IllegalStateException("a is false");
}
System.out.println("i = " + i);
}
}
''')
{code}

> Key: GROOVY-10580
> URL: https://issues.apache.org/jira/browse/GROOVY-10580
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 4.0.1
> Reporter: V
> Priority: Major
>
> Running the following in `groovyConsole`:
> {code:groovy}
> final int i
> final boolean a = true
> if (a) {
> i = 1
> } else {
> throw new IllegalStateException('a is false')
> }
> println "i = $i"
> {code}
> would give me:
> {noformat}
> 1 compilation error:
> The variable [i] may be uninitialized
> . At [9:15] at line: 9, column: 15
> {noformat}
> It seems groovyc does not take throwing an exception as a non-reachable
> branch.
> This code is almost a verbatim copy from a java code that is working.
> This looks similar to GROOVY-8472, and a few others.
