3514057 - ASM assistedservicefacades methods always return null/false using OCC

When ASM extension is used on OCC with SAP Composable Storefront, the functionality is working fine (e.g. storefront can access the ASM component, search for customers, emulate them, etc.). However, inside backend java classes, when checking which customer is emulated or if there's and agent logged in using the assistedservicefacade native methods the return is always null or false, it seems ASM_SESSION_PARAMETER is always null. The issue call stack is like below.
