Thrown to indicate that code has attempted to call a method handle via the wrong method type. As with the bytecode representation of normal Java method calls, method handle calls are strongly typed to a specific type descriptor associated with a call site. ...
返回Java 虚拟机中的内存总量。 traceInstructions(on) 启用/禁用指令跟踪。 traceMethodCalls(on) 启用/禁用方法调用跟踪。 三、常见的应用 1、内存管理: Java提供了无用单元自动收集机制。通过totalMemory()和freeMemory()方法可以知道对象的堆内存有多大,还剩多少。 Java会周期性的回收垃圾对象(未使用的对象),以便...
断点调试是我们最常使用的调试手段,它可以获取到方法执行过程中的变量信息,并可以观察到方法的执行路径。但断点调试会在断点位置停顿,使得整个应用停止响应。在线上停顿应用是致命的,动态调试技术给了我们创造新的调试模式的想象空间。本文将研究Java语言中的动态调试技术,首先概括Java动态调试所涉及的技术基础,接着介绍我...
