      Install BPM Suite 6.4.9 on Tomcat on Windows; Set storesvgonsave to true; Start the server, create a business process; Open the business process, modify it, save it; Notice the exception in logs; If you deploy the project will see that it will always use the first version of the process SVG;

      When running BPM Suite on Windows and setting storesvgonsave to true the SVG is only generated at first time, when you edit and save the process the SVG will not be updated and the following exception will be printed in the logs:

      When debugging the issue we noticed that it tries to delete a file using a bad slash (slash for Windows systems), see:

      INFO [http-nio-8080-exec-2] org.apache.catalina.core.StandardWrapperValve.invoke DEBUG deleting asset in path: /MyProject/src/main/resources/org/myapp\myprocess-svg.svg

      Notice the last slash is changed. The reason why it happens is because TransformerServlet uses File.separator to merge the path to the SVG, but paths in repository seems to use linux slash.
