Locale.getDefault bug in JDK 1.7

R

Roedy Green

I noticed that Locale.getDefault is returning the wrong locale in JDK
1.7. It used to work fine. It is not returning USA even though my OS
is configured as Canada.

Here is an SSCCE

I wonder if someone with a non-US locale could try this. I would like
to know if the problem is with my copy of Windows 7 64-bit or with my
copy of the JDK.

It is best to post everything. The problem most often is in the stuff
you don't post, in this case your class definition.

I think he did post the whole thing, and there is no class declaration.

The compiler seems to be totally confused, which would be consistent
with that. It would not even be considering a method declaration. It
looks as though its last try was to parse it as an annotation, which can
appear before the first class declaration.

Confusingly, at least via Google Groups here, these last two posts appeared in a thread entitled "Locale.getDefault bug in JDK 1.7". Is this just on my end?

The original post that described a bug due to a missing class declaration was answered in its own thread pretty well already.

I think what you have to do is post WHILE you are still reading
messages.

Now has anything to report on the JDK 1.7 Locale.getDefault bug?

If anyone does, could you post it to the original post? This thread has
devolved into off-top discussion for locale issues.

I'm confused. It is *NOT* returning USA? Even though your OS is set to CA?

What do you expect it to return?

Roedy's output shows that the locale default is US. However, it doesn't show how he thinks the OS is set to CA; presumably it's set in his BIOS or other low-level. I'd like to see Roedy's program expanded to show the results of 'getDefault()' after a 'setDefault()' to Canada. I'd also like to seethe values of the OS's LANG and LANGUAGE envars, or equivalents. Finally,I'd like to see what Java has for the user.language, user.country, and user.variant system properties.

Blast. That is a DSK typo I meant to write
It is noW returning USA even though my OS

One of the disadvantages of the DSK layout, with common letters close
to each other, is typos become valid words rather than gibberish.

I have windows 7 64 bit. I set the country and language in the control
panel. Windows does not export user.country and user.language to the
set environment. You have to get at it programmatically.

Here is the SSCCE with the changes you requested. It works ok with JDK
1.6 but not 1.7 on Windows 7 64 bit.

To see the problem, configure your windows 7 to a country something
other than USA, then run this SSCCE under JDK 1.7 (and perhaps other
combinations).

Do you think you are being sufficiently disingenuous there, Silvio?

It's obvious from the context that Roedy was talking about typing and key positions.

It's equally obvious to me that you were being deliberately disingenuous in your response to Roedy.

Is that really the best way for you to contribute to this newsgroup?
