Your suspicions are correct: an interceptor may be invoked by several
threads concurrently. For instance:
class TimingInterceptor implements MethodInterceptor {
private final Stopwatch stopwatch;
TimingInterceptor(Stopwatch stopwatch) {
this.stopwatch = stopwatch;
}
@Override Object invoke(MethodInvocation i) throws Throwable {
stopwatch.reset();
try {
return i.proceed();
} finally {
System.err.println("Invocation time: " + stopwatch.get());
}
}
Is going to break, because the stopwatch is shared among threads.
