在垃圾回收期间,运行时遍历所有线程的堆栈寻找托管根(局部变量在托管方法的帧中拥有对象的引用,需要被报告给GC,以保持对象活跃和跟踪,并且如果GC决定压缩堆,则可能跟踪它们的动向)。 在一些平台上,异常处理的过程中,会使用堆栈遍历器(第一遍寻找句柄,第二遍展开堆栈(unwinding the stack))。 各种各样的方法,通常是...
1) stack unwinding 栈展开 1. Stack unwinding is a common way to implement exception handling mechanism, and it could be used by both compiler and JVM. 栈展开是被编译器和Java虚拟机普遍使用的一种实现异常处理机制的方法。 更多例句>> 2) extending virtual stack 扩展虚拟栈 3) protocol ...
栈异常处理 一个函数(或方法)抛出异常,那么它首先将当前栈上的变量全部清空(unwinding),如果变量是类...
警告:此答案尝试回答「为什么」,但为了准确性,用词可能稍繁琐。
thread->disable_stack_yellow_zone();if(thread->thread_state() == _thread_in_Java) {// Throw a stack overflow exception. Guard pages will be reenabled// while unwinding the stack.stub = SharedRuntime::continuation_for_implicit_exception(thread, pc, SharedRuntime::STACK_OVERFLOW); ...
Java Virtual Machines(JVM) put Java stack(Java method calls) and native stack(Native method calls in VM) into one stack, and perform stack unwinding using a Managed to Native Frame, known as M2NFrame. Some JVMs keep two stacks separately. TheXssset the size of the Java Stack in most ...
I suspect full 'unwinding' is unnecessary - can we walk the stack's return addresses given we're really just after a good stack trace to show how the overflow occurred. For the first cut a list of addresses would show how many frames were in the loop which is more info than none. (...
Java API importio.github.hexhacking.xunwind.XUnwind; 1. Initialize publicstaticvoidinit(); The only thinginit()does isSystem.loadLibrary("xunwind"). If you only use xUnwind in native code, no initialization is required. 2. CFI unwinding ...
