Hi,
Please review my change to prevent a startup crash on earlier versions
of MacOS.
Bug: https://bugs.openjdk.java.net/browse/JDK-8187772
Webrev: http://cr.openjdk.java.net/~bchristi/8187772/webrev.00/
When a non-default currency is set in the Language & Region control
panel, it's reflected as a variant in the locale identifier string. For
example, "en_US@currency=RUB" for U.S. English using the Russian rubles
currency.
convertToPOSIXLocale() is not expecting such variants, nor such a long
string. The result is a SEGV from memmove() on line 161. (Additional
details are in the bug report.)
The fix truncates the string passed to convertToPOSIXLocale() before any
'@'-denoted variant tags.
FWIW, the crash only happens on MacOS 10.10 and earlier because later
versions of MacOS always return a region along with the language (line
65), so we don't need to query the locale identifier (line 84) to
determine the region (hyphenPos is never NULL on line 82).
Thanks,
-Brent
