Abstract
A method and system for detecting and recovering from errors in trace data is provided. The trace data records selected events for executing routines, and the routines corresponding to the events are represented as one or more nodes in a tree structure. The events may be entries and exits to executing methods. A trace record identifying a routine is read, and an error condition is detected in which the identified routine does not match a routine corresponding to a current node in the tree structure. The tree structure is searched for a node that corresponds to the identified routine. Performance statistics, such as execution time, are attributed to nodes in the tree structure. In response to a determination that the current node is a root node of the tree structure, then a new node for the identified routine is added to the tree structure as a child node of the root node and spliced into the tree at the root node.
