3rd party jar files for a custom process extensions

Hello,

I created a process extension which uses third party jar files such as commons-vfs2-2.0.jar, commons-httpclient-3.1.jar etc and I put those jar files in the directory $AGILE_HOME\agileDomain\lib as recommended in the  Developer Guide: Developing Process Extensions under the topic "3.9 Best Practices for Copying third Party JAR Files"

As far as this PX is concerned, it is working fine. However I am concerned whether it will break any of the standard functionality of Agile and/or other custom PXs.

We are on Agile PLM 9.3.2.

Please advise, if this is right approach or else if there is any better approach to deploy the 3rd Party libraries that are required for custom PXs.
