Description

The CmpUtil.getCmpImplClassName() method has logic to handle classes with no package names. Unfortunately, that logic is not correct. The line

String cmpImplClass = ejbClass.substring(0, ejbClass.lastIndexOf('.'));

Will result in a StringIndexOutOfBoundsException if no "." is found in the classname because substring(0, -1) is not a valid string range.
