Without classes caching in ConfigurableClassLoader, we encounter very slow execution for signed jar classes.

This ticket allows specifying class that we want to force caching.

Resolution selected:

When using ConfigurableClassLoader (tccl) define a system property named talend.tccl.cacheable.classes which contains a list of cacheables classes prefixes separated by ,.
Sample

System.setProperty("talend.tccl.cacheable.classes", "org.apache.ziplock.JarLocation,com.ctc.wstx.stax");

When this property is set all classes starting by the prefixes will be cacheables. Ie:

• org/apache/ziplock/JarLocation.class will use cache.
• org/apache/ziplock/Archive.class will NOT use cache.
