其中class version是编译打Jar包后字节码文件的版本,有如下对应关系: Java release > Class version 8 > 52 9 > 53 10 > 54 11 > 55 12 > 56 13 > 57 14 > 58 15 > 59 16 > 60 17 > 61 18 > 62 19 > 63 21 > 65 所以假设你的Jar使用jdk21发布的,然后你在jdk8的runtime导入,编译时就...
Caused by: org.springframework.core.NestedIOException: ASM ClassReader failed to parse class file - probably due to a new Java class file version that isn't supported yet: file [C:\App.class]; nested exception is java.lang.IllegalArgumentException: Unsupported class file major version 65 at o...
其中attribute_length为属性的长度,sourcefile_index指向常量池中值为源代码文件名称的常量,在本例中SourceFile属性截图如下: 其中attribute_length为0x00000002表示长度为2个字节,而soucefile_index的值为0x0012,查看常量池的第18个常量可以知道源代码文件的名称为TestClass.java...

I have a project that has been compiling successfully using Java 17.0.7 and Spotbugs 4.7.3 via Gradle. When I upgrade to jdk-21, the build starts to fail as it appears that spotbugs does not understand the JDK-21 created .CLASS files. Is...
java类文件是一个8位字节的二进制流。数据顺序项存储在没有填充的类文件的相邻的项目之间。没有填充有助于保持紧凑的类文件,超过一个字节的数据是分成几个连续的字节,出现在高位字节顺序中。 就像java类可以包含不同数字的字段,方法,方法参数,局部变量等,java类文件也可以许多大小不同的项目或者数量从一个类文件到...
of("./test/target/classes/demo/ClassFileApiDynamicTest.class"), build); } } 运行后反编译生成的代码: public class ClassFileApiDynamicTest { public static void main(String[] var0) { System.out.println("Hello, World!"); } } 通过这个简单案例可以看出,这个 api 简直就是在 java 里手写汇编,...
