The only possible solution is: it needs a jar in tomcat's lib folder to load gdal-java JNI for any web application which uses it. Otherwise, when deploying a new petascope, tomcat must be restarted (reason: "Tomcat, uses separate class loaders for each of the web application, and it wont allow you load a same native library more than once to JVM via another class loader").
