ExE-Boss opened a new issue, #7949:
URL: https://github.com/apache/netbeans/issues/7949
### Apache NetBeans version
Apache NetBeans 23
### What happened
When any `switch` statement or expression has a nullable parameter and `case
null`, it won’t implicitly throw a `NullPointerException`, so **NPECheck**
shouldn’t report a warning in that case.
### Language / Project Type / NetBeans Component
_No response_
### How to reproduce
```java
@interface Nullable {}
enum SomeEnum { FOO, BAR, BAZ }
class Test {
void testSwitch(@Nullable SomeEnum someEnum) {
// incorrectly reports null warning on the next line:
switch (someEnum) {
case FOO -> { /* do stuff with FOO */ }
case BAR -> { /* do stuff with BAR */ }
case BAZ -> { /* do stuff with BAZ */ }
case null -> { /* do stuff with null */ }
}
}
}
```
### Did this work correctly in an earlier version?
No / Don't know
### Operating System
Windows 11
### JDK
OpenJDK Runtime Environment [Temurin](https://adoptium.net/)-23+37 (build
23+37)
### Apache NetBeans packaging
Apache NetBeans provided installer
### Anything else
_No response_
