@Public
public final class TemporaryClassLoaderContext
extends Object
implements AutoCloseable

Sets a context class loader in a "try-with-resources" pattern.

 try (TemporaryClassLoaderContext ignored = TemporaryClassLoaderContext.of(classloader)) {
     // code that needs the context class loader
 }
 

This is conceptually the same as the code below.

 ClassLoader original = Thread.currentThread().getContextClassLoader();
 Thread.currentThread().setContextClassLoader(classloader);
 try {
     // code that needs the context class loader
 } finally {
     Thread.currentThread().setContextClassLoader(original);
 }
