-------------------------------------------
Summary: Conversion from int to byte does not work in case of
ternary operator
Key: GROOVY-10081
URL: https://issues.apache.org/jira/browse/GROOVY-10081
Project: Groovy
Issue Type: Bug
Reporter: Stefanos Chaliasos
I have the following Groovy program.
{code:groovy}
@groovy.transform.CompileStatic
public class Main {
static byte x = 1;
public static byte foo() {
1
}
public static void main(String[] args) {
x = (true) ? 0 : foo() // this does not work
// the following works
if (true) {
x = 0
} else {
x = foo()
}
byte y = (true) ? 0 : foo() // this doesn't work as well
}
}
{code}
h2. Actual Behavior
The program does not compile, and I get the following error.
{code:java}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Main.groovy: 11: [Static type checking] - Possible loss of precision from int
to byte
@ line 11, column 9.
x = (true) ? 0 : foo()
^
Main.groovy: 20: [Static type checking] - Possible loss of precision from int
to byte
@ line 20, column 14.
byte y = (true) ? 0 : foo()
^
2 errors
{code}
h2. Expected Behavior
Compile successfully.
h2. Affected Version
This programs fails when compiled with the compiler from the master (commit:
