Selecting Methods: Constraints

•

Depends on nature of BCI library

─ May be circular dependencies with Java library

• Load-time instrumentation problem

─ JVMPI

─ Java-based BCI cannot instrument classes it uses

• Non-issue with static instrumentation

• Dynamic instrumentation adds significant

flexibility

─ Classes can be redefined after they are first used
