The problem is, with lithuanian collator, the generated collationkey does not
agree with collation order.
In other words: collator.compare("yi", "iy") !=
collator.getCollationKey("yi").compareTo(collator.getCollationKey("iy"))
Simple test:
{code}
import java.text.Collator;
import java.util.Locale;
public class TestLithuanian {
public static void main(String args[]) throws Exception {
Collator collator = Collator.getInstance(new Locale("lt"));
int value = collator.compare("yi", "iy");
System.out.println(value); // returns 1
int value2 =
collator.getCollationKey("yi").compareTo(collator.getCollationKey("iy"));
System.out.println(value2); // returns -1
}
}
{code}
Note that if you change java.text.Collator to com.ibm.icu.text.Collator, they
are consistent. Looks like a bug in JDK collation.
