Class IOHelper.SafeURLInputStream

java.lang.Object
  java.io.InputStream
      org.apache.tuscany.sca.contribution.service.util.IOHelper.SafeURLInputStream

All Implemented Interfaces:

java.io.Closeable

Enclosing class:

IOHelper

public static class IOHelper.SafeURLInputStream
extends java.io.InputStream

This class is a workaround for URL stream issue as illustrated below. InputStream is=url.getInputStream(); is.close(); // This line doesn't close the JAR file if the URL is a jar entry like "jar:file:/a.jar!/my.composite" We also need to turn off the JarFile cache.
