Native Query with equalsIgnoreCase Error

[mudzakkir]

Assalamu'alaikum.

I use db4o 7.4 version, and this is my code:

List katas = new ArrayList();
try {
container = Db4oConnection.getInstance().getObjectContainer();
katas = container.query(new Predicate() {
@Override
public boolean match(Kata kata) {
return kata.getKata().equalsIgnoreCase(string);
}
});
} catch (Exception e) {
JOptionPane.showMessageDialog(null, e);
}
if (katas.isEmpty() || katas == null) {
return string;
} else {
return katas.get(0).getMakna();
}

The error message is:


init:
deps-jar:
compile:
run:
Exception in thread "db4o server message dispatcher mudzakkir" java.lang.IllegalArgumentException: array element type mismatch
at java.lang.reflect.Array.set(Native Method)

at com.db4o.internal.handlers.array.ArrayHandler.read Into(ArrayHandler.java:400)
at com.db4o.internal.handlers.array.ArrayHandler.read Elements(ArrayHandler.java:377)

Look at this native Query Code:

container = Db4oConnection.getInstance().getObjectContainer();
katas = container.query(new Predicate() {
@Override
public boolean match(Kata kata) {
return kata.getKata().equalsIgnoreCase(string);
}
});

If I change the parameter like this:

return kata.getKata().equals(string);

The application not error, work fine.

But, i want the parameter in query is not case sensitive, so I input the parameter like that.

Any clue error please?...
