function-level call chain information

[Seanmc1005]

Dear rjust, I'm sorry to bother you, but is there any way for the Defects4J project to get function-level call chain information during the run of a failed test case? The error message for a failed test case sometimes does not contain the stack information of the call chain, so it would be nice if there was a way to get it. Look forward to your reply. Thank you very much.
