This can happen when assumptions made by an optimizing dynamic compiler have become outdated.

当执行优化的动态编译器做出的假设已经过时时，就会发生这种情况。

A dynamic compiler mitigates this cost by eventually compiling all the interpreted methods that are frequently called by JIT compiled code, but without a dynamic compiler, this cost can't be hidden.

动态编译器通过最终编译所有由JIT编译代码频繁调用的那些解释过的方法来减少这项开销，但是如果不使用动态编译器，则这项开销就不可避免。
