Password encryption

Hi

When I use stand-alone RapidMiner the password to the  database is  encrypted in the  xml process file, but when I switch to my own code,which use RapidMiner as a library and call
RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);
RapidMiner.init();
then the password is decrypted, and the  log file contains com.rapidminer.parameter.ParameterTypePassword decryptPassword
How can I change it? or force password encryption when RapidMiner is used as a library

Best
