-------------------------------------

             Summary: change String.replaceAll() to replace() to improve performance.
                 Key: CLOUDSTACK-10408
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-10408
             Project: CloudStack

(4) server/src/main/java/com/cloud/user/AccountManagerImpl.java

When the replaced string is not represented as a regular expression, the String.replace() should be used to gain a better performance since it does not perform pre-compiling, which may cost some additional time.
