Isaac Dooley commented on GROOVY-7284:
--------------------------------------

Here is a simple example that fails to compile in 2.5.2, but compiles 
successfully in 2.4.15.
{code:java}
final Object v
try {
     v = "hello world"
} catch (Exception e) {
     throw new RuntimeException("goodbye")
}

println v{code}
 
{code:java}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
./test2.groovy: 8: The variable [v] may be uninitialized
. At [8:9] @ line 8, column 9.
println v
^

1 error
{code}

> This is a brand new error the code used to compile just fine. For the 
> avoidance of doubt:
> $ grep fileText `find src -name "*.groovy"` 
> src/main/groovy/gant/Gant.groovy:      final fileText = url.text
> src/main/groovy/gant/Gant.groovy:      compileScript(cacheDirectory, 
> fileText, className)
> src/main/groovy/gant/Gant.groovy:      return 
> binding.groovyShell.parse(fileText, buildClassName)
> the variable is not in fact reassigned.
