Access to static field locked on instance data

Reports accesses to a non-constant static field which is locked on either this or an instance field of this.

Locking a static field on instance data does not prevent the field from being modified by other instances, and thus may result in surprising race conditions.

Example:

  static String s;
  def foo() {
      synchronized (this) {
          System.out.println(s); // warning
      }
  }
