Re: Findbugs and locks?

Sorry for the confusion, I too quickly posted an experimental version.
I can't figure out what exception path the following might close, but
FindBugs does not produce a bug report for the following:

import java.io.IOException;
import java.util.concurrent.locks.ReentrantReadWriteLock;
import java.util.concurrent.locks.ReentrantReadWriteLock.WriteLock;

public class SSCCE {

  static ReentrantReadWriteLock lockArray[];
  static {
    lockArray =
      new ReentrantReadWriteLock[5];
    for (int i=0; i<lockArray.length; i++)
      lockArray[i] = new ReentrantReadWriteLock();
  }

  static void method(int n) throws IOException {

    WriteLock lock = lockArray[n].writeLock();
    lock.lock();
    try {
      // do some disk I/O
    } finally {
      lock.unlock();
    }
  }

  public static void main(String[] args) {}
}
