Can not select JAR files in "Generate RestEasy WAR" wizard

Designed a virtual procedure with REST based extension metadata, created VDB and trying to generate the WAR file from it. The "Create REST WAR File" wizard asks to select the "teiid-engine" and "teiid-common-core" jar files, but

1) Navigating through "browse" button will not let you select the jar file
2) Nor typing the whole path manually enable the "OK" button to finish.

(see attached picture)

Also, why would one need these files to be included in the WAR file? At best it needs to use the "teiid-jdbc.jar", even that not needed because it of use of the JNDI name. IMO, they should not be needed compilation, if needed, use the Designer's plugin-in which already has this dependency. MUST not need runtime dependency, unless the communication between the REST service and Teiid server is not over JDBC. Can not select JAR files in "Generate RestEasy WAR" wizard
