## PoC
```xml

com.google.firebase
firebase-admin
9.2.0

```

```java
import org.junit.Test;
import com.google.firebase.database.utilities.*;
public class UtilitiesFuzzerSplitIntoFrames {
@Test
public void splitIntoFramesFuzzerTest() {
try {
String[] result = Utilities.splitIntoFrames("9.", 0);
} catch (Exception e) {
}
}
}
```

Commencez par com.google.firebase.database.utilities.Utilities.splitIntoFrames dans Utilities.java:131 et reproduisez le rapport à l’aide du PoC UtilitiesFuzzerSplitIntoFrames avec l’entrée "9." et une taille de frame de 0. Déterminez le comportement attendu pour cette entrée et vérifiez que le comportement obtenu ne provoque plus l’épuisement du tas Java.
