RFR: 8006039 : test/tools/launcher/I18NJarTest.java fails on Mac w/ LANG=C, LC_ALL=C

[Brent Christian]

Hi,

This test started failing after 8003228 [1] was putback (setting 
sun.jnu.encoding to UTF-8 on Mac).  It tests if java is able to launch a 
.jar stored in a directory named with two-byte characters.

The code comments in the test case state that (on Unix) it expects 
LC_ALL to be set (to ja_JP.UTF-8/ja_JP.utf8/ja_JP.ujis), though it also 
seems to work with en_US.UTF-8).

Our automated build+test Macs have LANG=C, so the test has been 
"passing" without actually testing the functionality.

The test case determines if the environment is suitable for testing by 
checking if sun.jnu.encoding is either "MS932" or "UTF-8" (on Mac, this 
is now always UTF-8).  The test doesn't actually check LC_ALL.

I think the test should also check the LANG & LC_ALL env vars, and go 
back to "fake passing" the test if either is set to 'C'.  This would 
allow the test to continue to run "for real" in the default Mac 
environment (LANG=en_US.UTF-8), and stop the test from failing on the 
build+test Macs.

Of course it would be even better to update the test so the automated 
test machines actually test the intended functionality.  On UNIX at 
least, perhaps it could find something suitable to set LC_ALL to before 
attempting to launch the .jar.  I can file a separate bug for this.
