This part sounds potentially dangerous to me:
We develop an OSGI Eclipse E4 based application which is written in a combination of Java and Groovy. The application makes use of Groovy templates dynamically loaded at runtime (to facilitate providing HTML reports) and provides provision for the user to provide Groovy scripts which are parsed and run by a GroovyShell at runtime. Is this user provided Groovy shell code somehow isolated from application code ? If not that sounds dangerous to me, and can cause unexpected side effects. Or are all users experienced developers with deep understanding of the application? Even if so I'm skeptical.
