Some customers have strict security policies and they are not allowed to use password as cleartext.
you can encrypt the password with the following command:
Request.Management_Request.Management_3_1_3+hf.1.build.1415.package\tomcat-libs>java -cp btm-2.1.3.jar bitronix.tm.utils.CryptoEngine
Bitronix Transaction Manager 2.1.3 password property crypter
Usage: CryptoEngine <password> [cipher]

[cipher] is optional and is the cipher to be used to crypt the password
