- Subject: FYI: java.io: Use correct lock for chained writers
Chained Readers and Writers should synchronize on the existing lock used
by their inferior. In some cases we were not doing this. I'm checking in
this patch to fix it.
Regards

* java/io/BufferedWriter.java (BufferedWriter): Use existing lock
of chained Writer when calling super-constructor.
* java/io/FilterWriter.java (FilterWriter): Likewise.
* java/io/PrintWriter.java (PrintWriter): Likewise.
