Hello, What strikes me the most is the fact that old Cocoon 2.x works fine (flawlessly) with OpenJDK 8 implementation :) It was a total shock!! for us. Even though you can't tell it is absolutely 100% compliant (someone should be writing TCK for this), you still find Java revision to be 1.0!!! in byte-code compiler recognition. So it is actually running Java 1.0 not 8 if you want Cocoon to compile your JSP/XSP pages :) - If you want to use java byte-compiling process by Cocoon Engine (e.g. XSP) Why? Because there is a Cocoon-own implementation of Java Compiler _HEADER_ which uses first revisions of Javac spec 1.0 spec :) - very SIMPLE javac implementation
setCookie_xsp.class: compiled Java class data, version 45.3 (looks like Java 1.0.2 from Sun:) https://ldapwiki.com/wiki/Java%20Versions%20And%20Running%20Programs Although if you compile your Java classes with standard Javac 8 Compiler and place them into WEB-INF/lib (.jar) or WEB-INF/classes you get the LATEST FULL version: Config.class: compiled Java class data, version 52.0 (Java 1.8) Unfortunately all those "beauties" were thrown out in the Cocoon3.0 :( (even Cocoon 2.x doesn't have that kind of FLEXIBILITY and interchangability of Java Compilers). New releases were trimmed down to have only neccessary basic blocks of functionality, but as you see OLD Cocoon can suprise everybody with its "modern vision of PREDICTABLE future requirements". And that is absolutely AWESOME! Brilliant!!! I'm so disappointed that Continuations were thrown out as well as Jasper Engine 1 (JSP) that cannot inject its own code into "compilation Unit" - that is why XSP is no longer supported. The programmers believed it was too COMPLICATED to further manage that kind of Code. Jasper Engine 2 is also very small and trimmed down to be as small as possible. Maybe it's right, but for some reasons this might be a flaw in the Palette of available tools. With the 1990's technology and software we could make our Computers fly to the Moon and even beyond. With the current technology stack we cannot leave the Earth Surface ;) We made our Life simpler and more comfortable but in my opinion we lost some bigger picture of what important is when it comes to Software. Maybe I'm old protagonist yet a stubborn Backer of Simplicity in the World (after da Vinci) but this trend to slim down every single piece of component will head us into Lemmings world, where every one of us is a hard working specie to achieve something that could be achieved long long before the Computers were born, easier, faster and wiser :) But there is at least one good sign on the Horizon. Not everything is going commercial and not everything Open-Source is getting slimmed down (for addons you have to pay!). If you take into the consideration that future Oracle Java updates/releases will be commercial/paid only via subscriptions :( most of Open-Source World is switching to OpenJDK now :) Greetings, Greg wt., 5 lut 2019 o 11:56 gelo1234 <gelo1...@gmail.com> napisał(a): > Hello Senthilkumar, > > The problem is related to String Pool implementation that has changed in > the Java 8 spec.
