Class NonClosingJarInputStream

java.lang.Object

java.io.InputStream

java.io.FilterInputStream

java.util.zip.InflaterInputStream

java.util.zip.ZipInputStream

java.util.jar.JarInputStream

org.apache.tomcat.util.scan.NonClosingJarInputStream

All Implemented Interfaces:

Closeable, AutoCloseable

public class NonClosingJarInputStream
extends JarInputStream

When using a JarInputStream with an XML parser, the stream will be closed by the parser. This causes problems if multiple entries from the JAR need to be parsed. This implementation makes {close() a NO-OP and adds reallyClose() that will close the stream.
