### Question
Hi, I auto generate code in a `build.gradle.kts` file. Now I want to
serialize the data in kotlin. On my application startup which is written in
Java I want to read the file from the resources folder.
Serializing an empty `Map` works in Kotlin(when deserializing it afterwards
in Java) but when adding an object to the Map it starts throwing this error
(deserializing in java). When serializating from within Java, with the exact
same object added to the map it works though.
```

```
Serialization:
```kotlin
val fury: Fury = Fury.builder().withLanguage(Language.JAVA)
.requireClassRegistration(true)
.withRefTracking(false)
.build()
KotlinSerializers.registerSerializers(fury)
fury.register(Emoji::class.java)
fury.register(EmojiGroup::class.java)
fury.register(EmojiSubGroup::class.java)
fury.register(Qualification::class.java)
val emojiMap: MutableMap<String, Emoji> = mutableMapOf()
emojiMap["test"] = Emoji(
"🤼",
"\\uD83E\\uDD3C",
"🤼",
"🤼",
"%F0%9F%A4%BC",
Collections.unmodifiableList(Arrays.asList(":people_wrestling:",
":wrestlers:", ":wrestling:")),
Collections.singletonList(":wrestlers:"),
Collections.singletonList(":wrestling:"),
Collections.unmodifiableList(Arrays.asList("combat", "duel",
"grapple", "people", "ring", "tournament", "wrestle", "wrestling")),
false,
false,
3.0,
Qualification.FULLY_QUALIFIED,
"people wrestling",
EmojiGroup.PEOPLE_AND_BODY,
EmojiSubGroup.PERSON_SPORT,
false
)
FileOutputStream(RESOURCES_PATH).use { out ->
out.write(fury.serialize(emojiMap))
}
```
Deserialization:
```java
static byte[] readFileAsBytes(final String filePathName) {
try (InputStream is =
EmojiManager.class.getResourceAsStream(filePathName); ByteArrayOutputStream
buffer = new ByteArrayOutputStream()) {
if (null == is) throw new IllegalStateException("InputStream is
null");
byte[] data = new byte[4096];
int bytesRead;
while ((bytesRead = is.read(data, 0, data.length)) != -1) {
buffer.write(data, 0, bytesRead);
}
return buffer.toByteArray();
} catch (IOException e) {
throw new RuntimeException(e);
}
}
public static void main(String... args) {
final Fury fury = Fury.builder().withLanguage(Language.JAVA)
.requireClassRegistration(true)
.withAsyncCompilation(true)
.withRefTracking(false)
.build();
fury.register(Emoji.class);
fury.register(EmojiGroup.class);
fury.register(EmojiSubGroup.class);
fury.register(Qualification.class);
Map<String, Emoji> map = (Map<String, Emoji>)
fury.deserialize(readFileAsBytes("/single"));
}
```
