Locale instances are shared by different PMs (when in use as FCO)
-----------------------------------------------------------------
Key: JDO-397
URL: http://issues.apache.org/jira/browse/JDO-397
Project: JDO
Issue Type: Bug
Reporter: Ilan Kirsh
Tests in org.apache.jdo.tck.models.fieldtypes are using fields of Locale that
are defined as FCO. The definition is only a hint to the implementation but
when a FCO is actually used, the same JVM static Locale instances are persisted
using different PersistenceManagers and tests fail.
The solution:
In org.apache.jdo.tck.models.fieldtypes.TestUtil lines 142-148:
case(5):
vec.add(0, Locale.CHINA.clone());
vec.add(1, Locale.FRANCE.clone());
vec.add(2, Locale.GERMANY.clone());
vec.add(3, Locale.JAPAN.clone());
vec.add(4, Locale.ITALY.clone());
break;
similar to cloning strings few lines above:
case(3):
vec.add(0, new String("Hello"));
vec.add(1, new String("Welcome"));
vec.add(2, new String("To The"));
vec.add(3, new String("Beautiful"));
vec.add(4, new String("World"));
break;
And also in org.apache.jdo.tck.pc.fieldtypes.AllTypes:
public static final Locale[] Locale_values = {
(Locale)Locale.US.clone(),
(Locale)Locale.UK.clone(),
(Locale)Locale.FRANCE.clone(),
(Locale)Locale.GERMANY.clone(),
(Locale)Locale.CANADA.clone(),
(Locale)Locale.JAPAN.clone(),
(Locale)Locale.ITALY.clone(),
(Locale)Locale.CHINA.clone(),
(Locale)Locale.KOREA.clone(),
(Locale)Locale.TAIWAN.clone()
};
similar to cloning strings few lines above:
public static final String[] String_values = {
new String(""), new String("hello world"),
new String("JDO has a very nice persistence API"), new String("JDO"),
new String("Java"), new String("abcde"),
new String("abcdef"), new String("JDO is a breeze to use"),
new String("Java"), new String("Long-live JDO")
};
