JasperSoft Studio hangs testing data adapter Beans Collection

It also happens with official example: http://community.jaspersoft.com/documentation/tibco-jaspersoft-studio-user-guide/v611/working-collection-javabeans-data-adapter

This doesn't occur if I install Jasper plugin on Eclipse instead of the Studio Complete downloaded from sourceforge.

It works fine when you generate a JAR file with the lower Java version (eg. 1.8).

Changed Resolution from Open to Unable to Reproduce

Changed Status from New to Closed
