There have been complaints about the new java script library from the very beginning. If you hop over to the official P11 forum at RDNA and search, there is a thread on using the Flash/Air library from the previous version if you have it installed. Shaderworks library manager works in P11 as does D3D's Python based library app sold here at Rendo. There is a free light version of P3do Explorer you can try as well.
