ETL tool not exiting with 3.1.1

Dear All,

I am trying to use the Orient DB oetl.bat module to create a Orient DB database and load data into it from a CSV file.
Unfortunately, the oetl.bat never exits or gives out any message regarding the execution of the program. Due to this I am unable to track the data loading process or know the time taken for the loading.

Is anyone facing the same issue. Please help.
