When trying to execute JPublisher with JDK 1.8, there is an error reported. While using JDK 1.7 all works fine.

Example:
1) JDK 1.8.0_112

c:\Java\jdk1.8.0\bin\java -cp c:\apps\oracle\product\12.1.0\client_1\sqlj\lib\translator.jar;c:\apps\oracle\product\12.1.0\client_1\sqlj\lib\runtime12.jar;c:\apps\oracle\product\12.1.0\client_1\sqlj\lib\sqljutl.jar;c:\apps\oracle\product\12.1.0\client_1\sqlj\lib\javax-ssl-1_1.jar;c:\apps\oracle\product\12.1.0\client_1\sqlj\lib\runtime12ee.jar;c:\apps\oracle\product\12.1.0\client_1\jdbc\lib\ojdbc7.jar oracle.jpub.Doit -user=<USER>/<PASSWORD> -props=C:\<PATH>\jpub.properties

Result:

2) JDK 1.7.0_80
c:\Java\jdk1.7.0_80\bin\java -cp c:\apps\oracle\product\12.1.0\client_1\sqlj\lib\translator.jar;c:\apps\oracle\product\12.1.0\client_1\sqlj\lib\runtime12.jar;c:\apps\oracle\product\12.1.0\client_1\sqlj\lib\sqljutl.jar;c:\apps\oracle\product\12.1.0\client_1\sqlj\lib\javax-ssl-1_1.jar;c:\apps\oracle\product\12.1.0\client_1\sqlj\lib\runtime12ee.jar;c:\apps\oracle\product\12.1.0\client_1\jdbc\lib\ojdbc7.jar oracle.jpub.Doit -user=<USER>/<PASSWORD> -props=C:\<PATH>\jpub.properties
