Feedback is on webrev.02
http://cr.openjdk.java.net/~chegar/7000511/webrev.02/webrev/ :
* PrintStream
- .flush(), close(), most println() methods synchronize on this for their
entire implementation. They could just be made synchronized methods.
I think there are pros and cons of doing this, maybe best left to
another CR which could look into this separately?
- The javadoc for append(CharSequence,int,int) for the csq==null condition
seems misleading as start and end are considered.
I'm not sure what the original intent of this was, but from what I can
see the javadoc appears to be clear and the implementation looks like it
behaves correctly.
* Formatter
- The zero params constructor could just call this((Apppendable) null). The
advantage is that the StringBuilder is only constructed in one place.
- The Formatter(Locale) constructor could just call this(l, (Apppendable)
null). Same reason.
Actually, I think it is clearer to have the StringBuilder created as is.
It makes it more obvious than having to trace through another
constructor. But it you feel strongly I can make the changes.

Failing java.io.PrintStream, java.io.PrintWriter, java.util.Scanner, and
java.util.Formatter multi-arg constructors that take a java.io.File or String
filename (as well as one or more additional args) opens a FileIn/OutputStream
to the given File/filename. If one of the other given args causes the
constructor to fail ( null or unsupported charset for example ) the
FileIn/OutputStream is never closed, and the application does not have a
reference to it. You rely on the finalizer to close the stream.
This is most serious on Windows because you cannot remove a file if there is an
open handle to it.
I also cleaned up an existing regression test that fails in samevm mode
(partly) because of this. And removed another excluded test from the list since
its bug was fixed some time ago.
