javassist cannot work on jdk17

Calling CtClass.toClass(ClassLoader loader, ProtectionDomain domain) renders the following error:

Caused by: java.lang.reflect.InaccessibleObjectException: Unable to make protected final java.lang.Class java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain) throws java.lang.ClassFormatError accessible: module java.base does not "opens java.lang" to unnamed module @6659c656 at java.base/java.lang.reflect.AccessibleObject.checkCanSetAccessible(AccessibleObject.java:354) at java.base/java.lang.reflect.AccessibleObject.checkCanSetAccessible(AccessibleObject.java:297) at java.base/java.lang.reflect.Method.checkCanSetAccessible(Method.java:199) at java.base/java.lang.reflect.Method.setAccessible(Method.java:193) at javassist.util.proxy.SecurityActions.setAccessible(SecurityActions.java:159) at javassist.util.proxy.DefineClassHelper$JavaOther.defineClass(DefineClassHelper.java:213) at javassist.util.proxy.DefineClassHelper$Java11.defineClass(DefineClassHelper.java:52) at javassist.util.proxy.DefineClassHelper.toClass(DefineClassHelper.java:260) at javassist.ClassPool.toClass(ClassPool.java:1240) at javassist.CtClass.toClass(CtClass.java:1392)

Very frustrating but it looks like it's a limitation of JDK. Hopefully, there is a workaround for 17, it seems 18 has no hope.
