A method for dynamically transforming bytecode of Java Virtual Machine (JVM) bootstrap classes during program startup uses a JVM agent to intercept startup of a JVM compliant computer program to transform the bytecode of already loaded JVM bootstrap classes and store the resulting set of ...

在前面我们提到过 MethodAccessorImpl 是通过 MethodAccessorGenerator#generate 生成动态字节码然后动态加载到 JVM 中的。 其中生成 invoke 方法字节码的是MethodAccessorGenerator#emitInvoke。 我们看其中校验参数的一小段代码: // Iterate through incoming actual parameters, ensuring that each // is compatible with...

Fast reflection: the Java libraries now generate bytecode stubs for frequently used reflective objects such as Methods and Constructors. This technique exposes the reflective invocations to the Java HotSpot compilers, yielding much higher performance and, in some cases with the Server VM, complete eli...

It dynamically converts Java bytecode into native machine code at runtime, allowing the JVM to execute Java programs more efficiently. This process occurs transparently, without the need for manual compilation or intervention. By compiling frequently executed code paths into native code, the JIT ...
