Well python is not alien, since we ship a tiny (~1.7Mb) python run-time with every copy of LibreOffice we ship; ie. it is more built-in than Java which is (sadly) not ubiquitous, and 10x larger. Incidentally, the side effect of not having Java around, or worse having a broken / mis-detected Java on an install is a slew of annoying dialogs when you start LibreOffice from the various extensions that want it; eg. five in a row of the form: "Can I annoy you right now ?! [yes!]" ;-) a terrible user experience. I'd like to loose that: indeed working on that would help reduce the need to prune Java stuff. The other option of shipping a vast chunk of cruft we don't need to bundle, and use almost none of is less attractive. Furthermore, Java has this unpleasant GC that complicates debugging by hooking various signals, and has in the past caused all manner of problems: eg. leaving invalid guard pages around on the stack causing apparently un-related crashes later, and so on. ie. I would really like to see Java relegated to a nice-but-optional thing that in practise is not on the hot path for most people. > I guessed the replacement of Java is to eliminate integration issues. Primarily; true. However, Java's startup performance is mythically terrible; eg. porting from Java -> C++ for the flat ODF export turned a four seconds export (for a simple file, the first time) down to sub one second. This is not the case for our embedded python I think. > If that's not the case... whats the problem with Java? Just the > "is a appropriate JRE / JDK installed" issue?. Sorry, perhaps > a noob question Not at all - a good question :-) I appreciate if your mission is to drive Java deployment everywhere then perhaps the answer is not one that everyone will like. Perhaps the best thing to do for Java is to try to work on the C++ code paths, and error notification code for cases where it is not present, particularly on Windows.
