Applications are expected to handle these exception conditions and take necessary recovery actions such as releasing opened database connections. However, exception-handling rules that describe these necessary recovery actions are often not available in practice. To address this issue, we develop a novel approach that mines exception-handling rules as sequence association rules of the form \u201c(FC1c<sup>1<\/sup>\u2026FCc<sup>n<\/sup>) \u2227 FCa \u21d2 (FCe<sup>1<\/sup>\u2026FCe<sup>m<\/sup>)\u201d. This rule describes that function call FCa should be followed by a sequence of function calls (FCe<sup>1<\/sup>\u2026FCe<sup>m<\/sup>) when FCa is preceded by a sequence of function calls (FCe<sup>1<\/sup>\u2026FCc<sup>n<\/sup>). Such form of rules is required to characterize common exception-handling rules. We show the usefulness of these mined rules by applying them on five real-world applications (including 285 KLOC) to detect violations in our evaluation. Our empirical results show that our approach mines 294 real exception-handling rules in these five applications and also detects 160 defects, where 87 defects are new defects that are not found by a previous related approach.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Programming languages such as Java and C++ provide exception-handling constructs to handle exception conditions.
