A DESCRIPTION OF THE PROBLEM :
Compiling invalid sealed class Java source code using JavaC 22 causes infinite recursion in jdk.compiler/com.sun.tools.javac.code.Types.closure(Types.java:3707)

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Compilation should fail with error messages
ACTUAL -
SealedClassCompatibility4Mutated.java:7: error: interface expected here
    static interface SealedC1C33 extends Sealed {}
                                         ^
SealedClassCompatibility4Mutated.java:8: error: interface expected here
    static interface SealedD1C33 extends Sealed {}
                                         ^
SealedClassCompatibility4Mutated.java:4: error: cyclic inheritance involving SealedClassCompatibility4Mutated.Sealed
    sealed class Sealed implements SealedC1C33, SealedD1C33 {}
           ^
SealedClassCompatibility4Mutated.java:3: error: sealed class must have subclasses
    sealed class A implements Sealed, Comparable<A> {}
           ^
4 errors
