JSpecify

z```kotlin
implementation("org.jspecify:jspecify")

For Maven applications, you can define the JSpecify by adding the following to the `dependencies` block in the `pom.xml`:

```xml
<dependency>
    <groupId>org.jspecify</groupId>
    <artifactId>jspecify</artifactId>
</dependency>

Replace usages of io.micronaut.core.annotation.Nullable with org.jspecify.annotations.Nullable

Replace usages of io.micronaut.core.annotation.NonNull with org.jspecify.annotations.NonNull

When you find a Micronaut nullability annotation in a fully qualified type, the syntax is a bit different from JSpecify.

For example, this code is valid with Micronaut nullability annotations:

public ReadBuffer adapt(@NonNull io.micronaut.core.io.buffer.ByteBuffer<?> buffer) {

With the JSpecify nullability annotation, you need to change this code to:

public ReadBuffer adapt(io.micronaut.core.io.buffer.@NonNull ByteBuffer<?> buffer) {

For inner classes, Micronaut nullability annotations, you could do:

public FileChangedEvent(@NonNull Path path, @NonNull WatchEvent.Kind eventType) {

With JSpecify, you will need to change the code to:

public FileChangedEvent(@NonNull Path path, WatchEvent.@NonNull Kind eventType) {
