Good day!

I downloaded latest distribution of utPLSQL-cli and tried to execute it on my local environment. I copied ojdbc8.jar as was written in README and even orai18n.jar from Oracle website to utPLSQL-cli/bin folder. However I am receiving the following error:

$ ./utplsql run tech_user/1@ora12c
java.sql.SQLException: Locale not recognized

My NLS_LANG has the following value:

$ echo $NLS_LANG
AMERICAN_AMERICA.AL32UTF8

$ java -version
java version "1.8.0_77"
Java(TM) SE Runtime Environment (build 1.8.0_77-b03)
Java HotSpot(TM) 64-Bit Server VM (build 25.77-b03, mixed mode)

My database parameters:

select * from v$version;

--
Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production
PL/SQL Release 12.1.0.2.0 - Production
CORE 12.1.0.2.0 Production
TNS for Linux: Version 12.1.0.2.0 - Production
NLSRTL Version 12.1.0.2.0 - Production

select * from nls_database_parameters ;

I would greatly appreciate any help or suggestions.

Thank you in advance.
