errael opened a new issue, #9399:
URL: https://github.com/apache/netbeans/issues/9399
### Apache NetBeans version
Apache NetBeans 30
### What happened
Editing java file, get `the assigned value is never used`. This is not
accurate, should be no warning.
### Language / Project Type / NetBeans Component
_No response_
### How to reproduce
1. Edit the following `class Warn`
Observe the warning on the indicated line: `data = switch(o) {`
Note: it looks like the analysis is getting confused by the `throw`. Replace
the throw, like with `"j"`, and the warning goes away.
```java
package com.raelity.play.warn;
public class Warn {
public void f()
{
String data = null;
Object o = g(null);
if (o != null) {
data = switch(o) { // warn: the assigned value is never used
case Integer _ -> "i";
default -> throw new IllegalArgumentException();
};
}
g(data);
}
Object g(Object o) {
return 1;
}
}
```
