New Null Checks in Inner Class Constructors

Read Original

The article details a new Java 25 feature where the compiler (javac) will emit null checks for the enclosing instance in inner class constructors. This change prevents NullPointerExceptions from core reflection, method handles, or direct bytecode invocation passing null. It explains the impact on libraries and a temporary compiler flag to disable the checks.
