keytool error: java.io.IOException: Incorrect AVA Format

You tried to use the blackberry-keytool tool to create a self-signed Developer Certificate. The cn value for the dname parameter contains a special character. The special character set includes:

• Commas (,)
• Addition symbol (+)
• Quotation mark (")
• Back-slash (\)
• Angled brackets(< and >)
• Semi-colon (;)

Add a back-slash in front of the special character in your command line. The following shows an excerpt from an incorrect command line:

... -dname "cn="One, two, three" ...

The following corrects the excerpt above:

... -dname "cn=One\, two\, three" ...
