JIT::
+ * JIT-ed code is recompiled to less-optimized code when an optimization assumption is invalidated.
+
+ * Method inlining is performed when a method is considered as pure.
+ This optimization is still experimental and many methods are NOT considred as pure yet.
+
* Default value of +--jit-max-cache+ is changed from 1,000 to 100
* Default value of +--jit-min-calls+ is changed from 5 to 10,000
