Pack200

Here is the pack200 extracted from JDK 13. It is compatible with Java 8 and supports (JPMS) Java Platform Module System. You just need to use org.glavo.pack200.Pack200 instead of java.util.jar.Pack200.

It is published to Maven central. You can add dependencies on it in this way:

Maven:

<dependency>
  <groupId>org.glavo</groupId>
  <artifactId>pack200</artifactId>
  <version>0.3.0</version>
</dependency>

Gradle:

dependencies {
  implementation("org.glavo:pack200:0.3.0")
}

Compared with the pack200 implementation in JDK 13, the native implementation has been deleted, leaving only the pure java implementation, so you may notice some performance degradation.
