kandi X-RAY | jetty-alpn-agent Summary

jetty-alpn-agent is a Java library typically used in Security, TLS applications. jetty-alpn-agent has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub.

jetty-alpn-agent is a JVM agent that enables TLS ALPN (or NPN) extension support for Java 7 and 8 by transforming relevant Java classes using the correct Jetty alpn-boot (or npn-boot) JAR file for the JVM version in use. Starting with OpenJDK 1.8.0_252 the use of jetty-alpn-agent is not strictly required anymore since the standard ALPN APIs have been backported to OpenJDK 1.8.0_252 from Java 9. Using jetty-alpn-agent with OpenJDK 1.8.0_252 or later performs no class transformation; the -javaagent option can be left in the command line, but it is encouraged to remove it. Since no class transformation is performed with OpenJDK 1.8.0_252 or later, the libraries that provide the ALPN implementation must be aware of the backported standard API and use them to provide the ALPN implementation.

There's no alpn-boot requirement for Java 9+

That's because ALPN is built into Java starting in Java 9.
