Findbugs and locks?

Findbugs gives the warning "Method does not release lock on all exception paths" on a method like the one below. Could it be because the lock is from an array of locks and it can't determine which? Or is it because you could put code outside of the try/finally block that could leave without unlocking the lock? Any other ideas? It can't leave the method without unlocking can it?
ReentrantReadWriteLock lock[] = new ReentrantReadWriteLock[5];
for (int i=0; i<lock.length; i++)
lock[i] = new ReentrantReadWriteLock();
static void method(int n) throws IOException {
lock[n].writeLock().lock();
try {
// do some disk I/O
} finally {
lock[n].writeLock().unlock();
}
}
Thanks,
