Eric Milles updated GROOVY-11437:
---------------------------------
Language: groovy
> incorrect typing in nested ternary operator leads to type unsafety
> ------------------------------------------------------------------
>
> Key: GROOVY-11437
> URL: https://issues.apache.org/jira/browse/GROOVY-11437
> Project: Groovy
> Issue Type: Bug
> Components: Static Type Checker
> Reporter: Thodoris Sotiropoulos
> Priority: Minor
>
> I have the following program, which leads to an unexpected typing result
> during an LUB operation.
> {code:java}
> import java.time.*;
> import java.time.chrono.*;
> class Test {
> public static void main(String[] args) {
> LocalDateTime now = LocalDateTime.now();
> int x = 1;
> ((false ? 1 :
> (false ? x : (ChronoLocalDateTime<LocalDate>) now)) >= x)
> }
> }{code}
> h3. Actual behavior
> The code compiles, but I receive the following ClassCastException
> {code:java}
> Exception in thread "main" java.lang.IllegalArgumentException: Cannot compare
> java.time.LocalDateTime with value '2024-07-08T17:00:53.307529' and
> java.lang.Integer with value '1'

> at Test.main(test.groovy:9)
> Caused by: java.lang.ClassCastException: class java.lang.Integer cannot be
> cast to class java.time.chrono.ChronoLocalDateTime (java.lang.Integer and
> java.time.chrono.ChronoLocalDateTime are in module java.base of loader
> 'bootstrap')

> Tested against master (commit: c773e04ce402816b8f92c0318d08bde32e723eed)
