ParentLastClassLoader (Apache Synapse 3.0.1 API)

java.lang.Object
- java.lang.ClassLoader
- - org.apache.synapse.transport.utils.sslcert.adaptor.ParentLastClassLoader

```
public class ParentLastClassLoader
extends ClassLoader
```
The ParentLastClassLoader is needed because the OCSP/CRL feature for synapse uses a dependency jar from bouncyCastle version bcprov-jdk16-1.46.jar. Apache Rampart which is a synapse dependency for WS-Security also uses an older version of a bouncyCastle jar. The JVM loads the older version thus making OCSP/CRL feature fail to function. This is known as Jar Hell in java community. As a workaround, a Parent Last Class Loader is used to load the classes used by OCSP/CRL feature from the relevant jar files. The default class loader hierarchy in Java is Parent First. This custom ParentLastClassLoader overrides the default behaviour. If ParentLastClassLoader could not load a class it will delegate the job to the parent, the system class loader.
