Issue/Introduction

Z/OS Java Agent – PREP_PROCESS_FILENAME fails when wildcards are used in the dataset name

Example:  Using the following dataset pattern: UC4.AA00.##XXX000.XXYYZZ.X*

Results in the following error:

U00020408 Cannot log on as user '*CURRENT'. Error code: 'n/a', error description: 'com.ibm.jzos.ZFileException //'UC4.AA00.##XXX000.XXYYZZ.X*': fopen() failed; 
EDC5047I An invalid file name was specified as a function parameter.; errno=47 errno2=0xc00b0286 last_op=0 errorCode=0x0'.

Observations:
- The issue only occurs when wildcards are present in the dataset name.
- When using a fully qualified dataset name without wildcards, the function works as expected.

This will usually happen when ANONYMOUS_FT is used and a login object with an empty password is used
