Bug ID: 60259
Summary: getDateInstance() and getDateTimeInstance() hang
locale without fallback
Product: classpath
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: classpath
Assignee: unassigned at gcc dot gnu.org
Reporter: timo.teras at iki dot fi
[Using classpath bundled with gcc 4.8.2]
If LC_MESSAGES locale is unsupported, non-existant or does not match the
expected pattern AA[_bb] where AA=language (2 bytes) and bb=region (2 bytes),
the locale handler goes to infinite loop.
Simple test case:
export LC_MESSAGES=C.UTF-8
And run:
System.out.println(java.text.DateFormat.getDateInstance());
This is two related problems:
1. The code involved is in classpath/java/text/DateFormat.java:
getDateInstance() and getDateTimeInstance(). The exception handler calls
recursively itself and causes infinite loop as the fallback locale cannot be
instantiated (for some unknown reason).
2. The code in gnu/classpath/natSystemProperties.cc interprets C.UTF-8 as
user.language='C.' and no user.region (since no underscore). This triggers the
bug if system locale is not in the expected format.
