## Does MicroStream work with the Java Module System (Jigsaw)?

Yes, since version 2.2 we provide an all-in-one multi-release jar which is compatible with Jigsaw projects.\
This single jar solution was necessary because different MicroStream modules use the same packages, but the module system doesn't allow that multiple modules declare the same exports.

```markup
<dependency>
    <groupId>one.microstream</groupId>
    <artifactId>jigsaw</artifactId>
    <version>04.00.00-MS-GA</version>
</dependency>
```

## Can MicroStream handle Records

Due to reflection restrictions of records introduced in Java 15, they are currently not supported. \
Java 16 and Java 17 are showing the same behavior.
