Hi Joe,

As I have previously stated you copied the struct definitions instead of moving them outside the ifdef.

Serviceability folk: we are particularly interested in whether the use of ticks_no_class_load is deemed appropriate in this situation. Who will be consuming this value?

Since you have opted for the simple fix of having an exported but non-functional AsyncGetCallTrace instead of actually removing the symbol from the symbol files (which is the proposed solution in the bug report),

That would be a simpler solution semantically but the only way I can see to do that is to use a text replacement mechanism in the build files - as is done for the dynamic vtable symbols. I find that less appealing than simply exporting an interface that is configured to report an error (which is essentially what all the optional interfaces do under the minimal VM).

I would like you to include a comment about this in the source. Right now it's very unclear why there is an exported function that only returns an error.

As to the appropriate return value, I don't know. The only caller should be the Sun Studio profiler, and I'm not sure how it will handle this case if ever run. The possible return values aren't very well documented.

I guess we need to try and run it to find out.

Okay, do either of you feel strongly about how this should be fixed -- return an error or remove the symbol?
