an internal error or resource limitation prevents the Java virtual
machine from implementing the semantics of the Java programming
language; in this case,an instance of a subclass of
@H_502_7@VirtualMachineError is thrown.
JLS不再说明VirtualMachineError. “内部错误”是指JVM中的一个错误,所以我对这种情况并不感兴趣：面对JVM中的错误,所有的注册都是关闭的.但“资源限制”的情况呢？是否有任何操作由于资源限制而永远不会失败？
解决方法
This specification cannot predict where internal errors or resource
limitations may be encountered and does not mandate precisely when
they can be reported. Thus,any of the @H_502_7@VirtualMachineError subclasses
defined below may be thrown at any time during the operation of the
Java virtual machine:
因此在Java中,对于VirtualMachineError异常,不能保证有异常保证.所有异常保证都必须符合资格“…但是如果引发VirtualMachineError则不能”.这是Java与C不同的方式之一.
这也表明,在捕获VirtualMachineError异常时没有太多的意义,因为如果一个被抛出,程序处于未定义的状态.不幸的是包括OutOfMemoryError异常.不幸的是,因为如果几个任务之一失败,因为它需要太多内存,我们可能希望继续执行其他任务.
