类构造器不存在情境下IAE的错误抛出 #966
Description
Description
我们发现对于同一个测试用例，J9抛出IAE，但是Dragonwell抛出NSME。
Steps to Reproduce
>>> path_to_dragonwell-jdk8/bin/java -cp . TestLauncher
>>> path_to_dragonwell-jdk11/bin/java -cp . TestLauncher
>>> path_to_dragonwell-jdk17/bin/java -cp . TestLauncher
>>> path_to_dragonwell-jdk21/bin/java -cp . TestLauncher
>>> path_to_j9-jdk8/bin/java -cp . TestLauncher
>>> path_to_j9-jdk11/bin/java -cp . TestLauncher
>>> path_to_j9-jdk17/bin/java -cp . TestLauncher
>>> path_to_j9-jdk21/bin/java -cp . TestLauncher
实际结果：
dragonwell-jdk8:
Exception in thread "main" java.lang.IllegalAccessError: java.lang.Class
at TestLauncher.main(Unknown Source)
dragonwell-jdk11:
Exception in thread "main" java.lang.IllegalAccessError: java.lang.Class
at TestLauncher.main(Unknown Source)
dragonwell-jdk17:
Exception in thread "main" java.lang.IllegalAccessError: java.lang.Class
at TestLauncher.main(Unknown Source)
dragonwell-jdk21:
Exception in thread "main" java.lang.IllegalAccessError: java.lang.Class
at TestLauncher.main(Unknown Source)
j9-jdk8:
Exception in thread "main" java.lang.NoSuchMethodError: java/lang/Class.<init>(Ljava/lang/String;)V (loaded from D:\download\jdk\openj9\jdk-8u452-b09\jre\lib\rt.jar by <Bootstrap Loader>) called from class TestLauncher (loaded from file:/D:/Lab/TestJDoc/reduce/your_dir/ by sun.misc.Launcher$AppClassLoader@599f5fea).
at TestLauncher.main(Unknown Source)
j9-jdk11:

j9-jdk21:
Exception in thread "main" java.lang.NoSuchMethodError: java/lang/Class.<init>(Ljava/lang/String;)V (loaded from jrt:/java.base by <Bootstrap Loader>) called from class TestLauncher (loaded from file:/home/share/JSmith_main/your_dir/ by jdk.internal.loader.ClassLoaders$AppClassLoader@fe0d50b8).
at TestLauncher.main(Unknown Source)
Expected behavior
在基于上述结果审查 java/lang/Class 的代码后，我们发现并不存在形如 java/lang/Class.(Ljava/lang/String;)V 的构造方法。因此，Dragonwell 应抛出 NoSuchMethodError，而非 IllegalAccessError。
