Manually verified JCo destination, both ping and test works.
Ran the WebDynpro console sanity check tool. All tests green.
When the application then tries to create a Jco connection during runtime I get these logs in defaultTrace on EP:
Could not create JCOClientConnection for logical System: 'WD_BN_MODELDATA_DEST' - Model: 'class com.company.models.bn.BN'.
supplyCheckInfos ...Class casted to IExternalStandardCheckInterface is class com.sap.tc.webdynpro.check.jcodest.wdp.InternalJCODestAvailabilityCheckInterface$External
supplyCheckInfos ...Class cast issue CompUsage is class com.sap.tc.webdynpro.progmodel.components.ComponentUsage
Any suggestions ?
