A DESCRIPTION OF THE PROBLEM :
Enabling -Djava.security.debug=x509,ava affects how special characters in certificates are processed. The expected behavior is that debugging should not interfere with the normal encoding of certificate fields.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Step 0:
Generate a p12 file with a certificate with special characters

Step 1:
Compile provided source code
javac Main.java

Step 2:
Run class with
java -Djava.security.debug=x509,ava Main


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Display the special chars

ACTUAL -
No special chars displayed
