Subject: Re: JvmtiEnv::PopFrame() (jvmtiEnv.cpp)
To: Robert Field <###@###.###>

The current PopFrame implementation, which is contained in the assembly
interpreters, requires two adjacent non-native Java frames on the top of the
stack in order to work. The reason is that the topmost frame needs to make a
determination of what kind of code it is returning to in order to understand
whether it can trivially request a reexecution of the invoke in the caller
frame, or whether it needs to save and restore the incoming arguments before
a deoptimization. It might be possible to change this to support popping
across VM calls, but not for beta 2.

We are not going to fix this bug in tiger (please, see bug 5019123),
but we may consider to fix it in post-tiger releases.
