SAP Business Connector 4.8 throwing exception after update to Core Fix 13

[former_member476525]

Hello SAP community,

due to a change in the German tax authorities interface for electronic interchange, I need to update a SAP Business Connector to "Core Fix 13", as published on April, 16th. As SAP does no longer support 32-Bit systems, I also migrated the system from WIndows 7 to a clean Windows 10 64-Bit box.

Clean install of BC 4.8, 64-Bit, strong encryption works fine. The server starts and the web interface responds to queries. Next step: I installed Service Release 14, SAP Note 2697290. Restart of the service required, everything fine afterwards.

So I install Core Fix 13 by SAP Note 2677070 and follow all the instructions. Changing the CLASSPATH triple checked, installed additional VCRedist packages, etc. However, the process will start but the server will not respond to any queries. Instead, an exception is thrown in server.log:

"java.lang.NoSuchMethodError: com.wm.util.TimeWrappingProvider.access$000(Lcom/wm/util/TimeWrappingProvider;)Ljava/util/List;
at com.wm.util.TimeWrappingProvider$TimeMesuredTask.run(TimeWrappingProvider.java:45)
at com.wm.util.pool.PooledThread.run(PooledThread.java:109)
at java.lang.Thread.run(Thread.java:735)"

This method is part of client.jar and should be available.

I replaced the original SAP JVM 5 by the highest available patchlevel of JVM 5,6,7 and even 8 to no avail. Also no success in finding any SAP Note handling this exception.

I'm not sure if I don't see the wood for the trees by now or if there is something wrong with the Core Fix 13 package. Any idea about this issue is much appreciated. Thank you!
