nmatt opened a new issue, #8985:
URL: https://github.com/apache/netbeans/issues/8985
### Apache NetBeans version
Apache NetBeans 28 latest release candidate
### What happened
Invoking Find Usages or Call Hierarchy on an enum constructor fails with a
StringIndexOutOfBoundsException if the enum type has constants with
implementations (curly braces).
Exception stacktrace:
```
java.lang.StringIndexOutOfBoundsException: Range [74, -1) out of bounds for
length 115

### Language / Project Type / NetBeans Component
Java, Refactoring
### How to reproduce
In a Java project, create the following enum class:
```
enum Example
{
CONSTANT() { };
Example() { }
}
```
Then invoke Find Usages or Call Hierarchy on `Example()`.
### Did this work correctly in an earlier version?
No / Don't know
### Operating System
Windows
### JDK
21
### Apache NetBeans packaging
Apache NetBeans binary zip
### Anything else
This might not be a common operation for enum constructors, but in large
enum classes (constants with non-trivial implementations), it can actually be
quite useful. Another reason is that that having the cursor on the enum
constructor doesn't highlight the constants in the sidebar, unlike other usages.
