> DbImport on Hana DB hangs up on a read operation, eventually throwing a couple different exceptions. This seems like a race condition between two JDBC connections (one used for reverse-engineering, another - for warming up Cayenne AutoAdapter). The errors are different on different runs; occasionally DbImport even succeeds.
> For now the fix is to warmup the adapter prior to the import operation. Pretty ugly.
