pine3ree opened a new issue, #6119:
URL: https://github.com/apache/netbeans/issues/6119
### Apache NetBeans version
Apache NetBeans 18
### What happened
An "Abstract class `SomeClass` cannot be instantiated" appears when it
shouldn't.
This seems a class-variable name collision bug. Changing the variable name,
or reassigning it solves the issue.
### How to reproduce
Create a php file with the following content and open it:
```php
<?php
interface MyClassInterface
{
public function doSomething();
}
abstract class MyClass
{
public function doSomething()
{
}
abstract public function doSomethingElse();
}
class MySubClass extends MyClass implements MyClassInterface
{
public function doSomethingElse()
{
}
}
class MyClassFactory
{
public function buildObject(string $myClass)
{
if (class_exists($myClass) && is_subclass_of($myClass,
MyClass::class))
{
// This causes "can not be instantiated error"
$myObject = new $myClass();
// Just using another variable name prevents the bug
$myFQCN = $myClass;
$myObject = new $myFQCN();
}
}
// no error
public function createObject(string $myFQCN)
{
if (class_exists($myFQCN) && is_subclass_of($myFQCN,
MyClass::class)) {
$myObject = new $myFQCN();
}
}
}
```
### Did this work correctly in an earlier version?
No / Don't know
### Operating System
mint/ubuntu 22.04
### JDK
java-11-openjdk-amd64
### Apache NetBeans packaging
