One of Java's strong points has always been the amount of care to source and binary compatibility (Java 8 classes work fine on Java 20, source code only need minor modifications). I welcome the new restrictions since they make Java more secure and future-proof, but they have a price. There's lots of (framework) code that makes use of those loopholes and many Java projects already have issues with maintenance since it's not the 'hot stuff' anymore.
