---------------------------------------
Summary: Poor Error Handling: Empty Catch Block
Key: KARAF-4207
URL: https://issues.apache.org/jira/browse/KARAF-4207
Project: Karaf
Issue Type: Bug
Affects Versions: 4.0.3
Reporter: Eduardo Aguinaga
HP Fortify SCA and SciTools Understand were used to perform an application
security analysis on the karaf source code.
The method authenticate() in JaasSecurityProvider.java ignores an exception on
line 199, which could cause the program to overlook unexpected states and
conditions. In this case the attempt to authenticate is ignored which is never
a good idea.
