SAP JCO ClassLoaderException since ubgrade to FP4

Hello together,

after upgrading domino 901 to FP 4 it seems that the grant permission all to the jvm/lib/ext folder is not working anymore. An existing XPage application is not working anymore. The reason is a class loader access denied exception. The SAPJCO is located in the jvm/lib/ext folder of the server. After granting AllPermission it is working again, but this is not the desired solution.

I could not found anything documented in the IBM Documentation related to this topic.

Has anyone similar results or a solution for that

Greetings

Stephan
