<ul><li>The OpenJDK Quality Group is promoting the testing of FOSS projects with OpenJDK builds.</li><li>Starting with JDK 25, when javac is targeting release 25 or higher, it will emit null checks for the enclosing instances in inner class constructors.</li><li>This behavioral change may lead to new NullPointerExceptions in code that uses core reflection, method handles, or direct bytecode invocation to pass null as enclosing instance.</li><li>To prevent the emission of additional null checks, a temporary workaround flag (-XDnullCheckOuterThis=(true|false)) can be used.</li></ul>
