[8u] RFR: JDK-8147451: Crash in Method::checked_resolve_jmethod_id(_jmethodID*)

[Shafi Ahmad]

Hi,

 

Please review the small code change for bug: "JDK-8147451: Crash in Method::checked_resolve_jmethod_id(_jmethodID*)" on jdk8u-dev

 

Summary:

resolve_jmethod_id() is getting called with invalid jmethodID and there is no check for validity of the method id inside this function. So before calling resolve_jmethod_id() we should check its validity. 

This code change add this check. Also inside Method::is_method_id() we are not checking return value of method_holder(). It may return NULL if method id is not valid so I have added null check for this too.
