======================================================================
Closed Issues in 6.0.0.hotfix2 (This Release)

HK-6349
While using TCP transport, underscore ( _ ) was not supported in the
hawk_domain value. 
e.g. Using "-hawk_domain test_env" in the Hawk configuration files 
was not supported for TCP Transport. Note that "test_env" contains an
underscore.
With this fix, now underscore can be used in hawk_domain while using 
TCP transport. 

HK-6305
The Tomcat version 7.0.70 shipped with Hawk 6.0.0 had security
vulnerabilities. These vulnerabilities were addressed in Tomcat 
version 7.0.82. With this fix, Tomcat has been upgraded from version 
7.0.70 to version 7.0.82 to eliminate the security issues.

HK-6261
HTTP adapter available with Hawk 6.0.0 does not support TCP 
transport. With this fix, the HTTP adapter supports TCP transport.

HK-6298
In case of AMI application configured with TCP transport, if an AMI 
method returns a null value, then the AMI application throws null
pointer exception. This issue has been fixed now.
