Locale error: Supplied territory description 'english' is invalid when the plugin starts Derby DB

[dreadk2002]

Hi I have an error that seems to be from DerbyDB:

It seems the database cannot run because it gets it's Locale with an unexpected territory.
The Jenkins I use is v1.588, it runs on centos 7, but I don't know exactly what java is used. The tomcat jenkins uses has java 1.8, the project is compiled using jdk1.7.0_21(using ant), but I am not certain what java version is used by the job itself.
