Jhyde - The java hybrid debugger
Hermanns C, Kuchen H
Abstract
Until today the most common technique to debug Java programsis trace debugging. In this work we present two different debugging approaches for Java: declarative debugging, which has its origins in the area of functional and logic programming, and omniscient debugging,which is basically an extension of trace debugging. To benefit from the advantages of both techniques we have integrated them into a single hybrid debugger called JHyde. We use JHyde to debug an erroneous mergesort algorithm and mention important aspects of its implementation. Furthermore, we show that the efficiency of the declarative debugging method can be significantly improved by a new debugging strategy.
