A DESCRIPTION OF THE PROBLEM :
Deserialization of a javax.print.attribute.standard.MediaPrintableArea printer attribute fails when the serialization happened in a prior invocation of the program. Unclear what the nature of the initialization problem is, but it works during the same invocation of the program as the serialization. Exception message suggests a problem with the implementation of the javax.print.attribute.EnumSyntax.readResolve method call in sun.print.Win32MediaSize.

The stack trace suggests that the valid range test in readResolve is not functioning properly because of the fact that the range is in descending rather than ascending order--but that's just our guess. That is, it says zero is not a valid value because it doesn't fall in the range 0 to -1:

java.io.InvalidObjectException: Integer value = 0 not in valid range 0..-1for cl
ass class sun.print.Win32MediaSize
        at javax.print.attribute.EnumSyntax.readResolve(Unknown Source)
(see Error Messages for full stack trace)

My code is attempting to deserialize a javax.print.attribute.standard.MediaPrintableArea object. Depending upon the specific attributes, this either succeeds or fails (in our case, with the stack trace shown; there may be other similar problems we haven't encountered yet). The problem appears when there is a non-standard page size involved (in our test case with a Canon S750 driver and the 4 x 6 size [a size supplied with the Canon driver because of its potential use to print on expensive Canon photo paper]).

Note that this only seems to happen when the deserialization occurs as the program is initializing. In the course of a single program invocation, the deserialization operates correctly. If the serialization sits in Preferences when the program starts, it fails (odd--and frustrating since that's sort of the whole point of saving the media size).



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
You'll need a Windoze box (we tested on both XP and 2K w/ sp4 so either should be an okay testbed).

Get the Canon driver for the S750 from this URL:

http://consumer.usa.canon.com/ir/controller?act=SupportSearchResultsAct&keyword=S750&Submit.x=39&Submit.y=11

Click on Drivers and get the one for Win2K or XP.

Install it (you won't actually need a printer to see the problem).

Run the test program. When the printer dialog comes up, go to the Page Setup tab; choose the 4 x 6 Media and change the margins. Press the Print button (this serializes the attributes of the printer and saves them as Preferences).

The program now redisplays the Print Dialog with the deserialized attributes shown (you can verify this by checking the Page Setup tab). When you press Print or Cancel, the program terminates.

So far so good. We've successfully deserialized the media object.

Rerun the program.

When the program attempts to deserialize the attributes, it fails as described.

At this point you can actually go to the registry and find the Preferences on this path:

My Computer\HKEY_CURRENT_USER\Software\JavaSoft\Prefs\<test program package name | unnamed>\/<printer name here>

If you delete the entry for media, you'll note that the program can initialize and display the print dialog. That is to say, the media-printable-area entry deserializes correctly.

If you want to get back to the initial state, you can run the program with the parameter:

reinit

Or, just delete the entries from the printer's folder in the registry.

Finally, if you choose one of the standard media sizes (for which there's a static class value in the MediaPrintableArea class), there doesn't seem to be a problem. Custom page sizes cause problems too.



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Printer Dialog should display, with the last settings, without an error regardless of the paper/media setting.
ACTUAL -
When you use a non-standard paper size for the media value, deserialization of the MediaPrintableArea instance fails upon initialization of the program (oddly not when it happens in the same invocation of the program as the serialization).

CUSTOMER SUBMITTED WORKAROUND :
I assume that if I disect the MediaPrintableArea so that I'm actually saving the x, y, h, w, and units properties, I could create a new one. Haven't had time to try that, but that's the plan.

Additional customer info :
Some of the information was a bit confused. Several times, I mistakenly referred to the MediaPageSize class when I meant the Media class. It's the form/media that's the problem. But it may be a limitation of the design: there doesn't seem to be a way to create a Media instance that refers to a non-standard paper size in a way that looks like it could deserialize correctly--it's odd that it'll do it within the same JVM instance.
