PREP_PROCESS_FILENAME or Filelist VARA fails with User or password is invalid on Java Unix Agent

Issue/Introduction

After upgrading the Linux Agents from 21.x from the C-based version to the Java based version (21.x or 24.x) we have observed that both the PREP_PROCESS_FILENAME script command and the Filelist VARA do not work when the login object does not have a password specified. 

Please note that we use the Linux Java Agents with the non-authenticated mode that consists on:

1.  Agent is started with root permissions
2.  In the ini file we set the variable login_check=no
3.  We set in the corresponding  UC_HOSTCHAR* the variable ANONYMOUS_JOB=Y 

The error message we receive in the agent log and report is as follows:

U00011439 Cannot log on as user 'username'. Error code: 'n/a', error description: 'java.io.IOException javax.security.auth.login.LoginException: User or password is invalid.'.

When a password is provided in the login object, the issue is resolved and the object runs normally. However, this is not a viable solution for our environment, as our Linux user accounts typically do not have passwords.

Additional Information

Public Title: Incorrect handling of logon_check and ANONYMOUS_FT in case of file selections

Public Description: In case of file selections (e.g. via PREP_PROCESS_FILENAME or Filelist VARA) the ini parameter logon_check and host setting ANONYMOUS_FT were not considered as expected.
