io.netty.util.internal.NativeLibraryUtil Maven / Gradle / Ivy

This artifact provides a single jar that contains all classes required to use remote EJB and JMS, including
all dependencies. It is intended for use by those not using maven, maven users should just import the EJB and
JMS BOM's instead (shaded JAR's cause lots of problems with maven, as it is very easy to inadvertently end up
with different versions on classes on the class path).

/**
* A Utility to Call the {@link System#load(String)} or {@link System#loadLibrary(String)}.
* Because the {@link System#load(String)} and {@link System#loadLibrary(String)} are both
* CallerSensitive, it will load the native library into its caller's {@link ClassLoader}.
* In OSGi environment, we need this helper to delegate the calling to {@link System#load(String)}
* and it should be as simple as possible. It will be injected into the native library's
* ClassLoader when it is undefined. And therefore, when the defined new helper is invoked,
* the native library would be loaded into the native library's ClassLoader, not the
* caller's ClassLoader.
