[jira] [Created] (GROOVY-9786) SC: cast exception for variable
assigned within conditional blocks
Eric Milles created GROOVY-9786:
-----------------------------------
Summary: SC: cast exception for variable assigned within conditional blocks
Key: GROOVY-9786
URL: https://issues.apache.org/jira/browse/GROOVY-9786
Project: Groovy
Issue Type: Bug
Affects Versions: 2.5.13
Reporter: Eric Milles
Consider the following:
{code:groovy}
interface Zero {
def m()
}
class One implements Zero {
def m() { 'One' }
}
class Two implements Zero {
def m() { 'Two' }
}
boolean aaa() { false }
boolean bbb() { true }
@groovy.transform.CompileStatic
void test() {
Zero x
if (aaa()) {
x = new One()
} else if (bbb()) {
x = new Two()
}
x.m() // GroovyCastException: Cannot cast object 'Two@654d8173' with class 'Two' to class 'One'
}
test()
{code}
This case was recently converted from dynamic groovy -- where it executes fine -- to {{@CompileStatic}}.
