TransferZeroByteFile relaxed - YADE transfer fails if MinFileSize is not configured

Current Situation

• If SourceFileOptions / Directives / TransferZeroByteFiles is configured as relaxed and SourceFileOptions / MinFileSize is not set, YADE aborts execution with the following exception:

  [returnCode=99]com.sos.yade.engine.exceptions.YADEEngineInitializationException: [Source]com.sos.commons.exception.SOSInvalidDataException: input
  com.sos.yade.engine.exceptions.YADEEngineInitializationException: [Source]com.sos.commons.exception.SOSInvalidDataException: input
  	at com.sos.yade.engine.commons.helpers.YADEArgumentsChecker.validateAndAdjustSourceArguments(YADEArgumentsChecker.java:117)
  	at com.sos.yade.engine.commons.helpers.YADEArgumentsChecker.validateOrExit(YADEArgumentsChecker.java:25)
          ...
  

  • The cause of the exception is not immediately clear.
• Main cause:
  • YADE internally sets MinFileSize=1 when TransferZeroByteFiles=relaxed, but does not correctly handle the case where MinFileSize is not set.

Workaround

• Instead of using TransferZeroByteFiles=relaxed, use MinFileSize=1 to skip zero-byte files.

Desired Behaviour

• TransferZeroByteFiles=relaxed should work as expected when MinFileSize is not set.
• If the configuration is invalid or cannot be processed, the exception should clearly indicate that the problem is related to the MinFileSize configuration.
