SAP AS Java affected from commons-collection vulnerability?

Dear all,

we are running an PI AEX (AS Netweaver Java 7.4) and I recently heard about this vulnerability: What Do WebLogic, WebSphere, JBoss, Jenkins, OpenNMS, and Your Application Have in Common? This Vulnerability. |

I did a quick search in the Java Class Loader View from PIs NWA and did not find any Apache Library there. But as I would consider myself far from a J2EE expert I might easily looking in the wrong place.

So my questions are:

1. Do you know if the SAP Netweaver AS Java might be affected
2. How should I check, e.g. where to do that "grep" the above link mentioned

Many thanks and kind regards

Jens
