Subject [jira] Commented: (HARMONY-1973) [drlvm][jvmti]Some jvmti methorods return JVMTI_ERROR_INTERNAL on Jitrino/OPT
Date Thu, 26 Oct 2006 10:55:17 GMT
    [ http://issues.apache.org/jira/browse/HARMONY-1973?page=comments#action_12444851 ] 
            
Gregory Shimansky commented on HARMONY-1973:
--------------------------------------------

Vera, JVMTI uses its own special EM configuration, so if you specify another one there is
no surprise that it doesn't work. Jitrino.OPT doesn't support a lot of functions which are
necessary for JVMTI implementation, and returns errors when these functions are called. That's
the reason for internal error.

I suggest closing this issue as invalid.

> The following JVMTI methods return JVMTI_ERROR_INTERNAL on Jitrino in OPT mode:
>     SetBreakPoint 
>     Get[Set]LocalInt
>     Get[Set]LocalFloat
>     Get[Set]LocalDouble
>     Get[Set]LocalLong
>     Get[Set]LocalObject
>  
> SetBreakPoint  returns ERROR code when this method uses  appropriate arguments.
> Get[Set]LocalXXXXXX methods return ERROR code
>     -   when all used arguments are correct and method should return JVMTI_ERROR_NONE

>     -   if incorrect "slot" parameter is used and JVMTI_ERROR_INVALID_SLOT should be
returned
>     -   if variable is not appropriate type for the function is used and 
>         JVMTI_ERROR_TYPE_MISMATCH is expected.
> To reproduce this bug run test from attachment.
> This test getLI uses GetLocalInt(...) method using incorrect slot. It expects that VM
returns 
> JVMTI_ERROR_INVALID_SLOT. But Harmony returns JVMTI_ERROR_INTERNAL.
