Description: I work under Linux KUbuntu 16.04, 64 bits, with KDE. Having installed "LanguageTool--3.9.oxt", and "NLPSolver.oxt", when I try to activate nlpsolver, I get the error message : "java.lang.reflect.InvocationTargetException" In Calc, it is not possible to solve non linear problems, such as minimising the sum of the squares of differences, depending on two parameters. "Tools > Solver..." When disabling "LanguageTool", it doesn't help. When removing "LanguageTool", the problem is solved and non linear problems can be solved. I'm not the only one with this issue, c.f. https://code.google.com/archive/p/ooo2gd/issues/115 Steps to Reproduce: 1. Install LanguageTool-3.9.oxt and activate it, if it is not already done 2. Install NLPSolver (from synaptic for example) 3. Activate nlpsolver 4. try to solve with "Tools > solver..." a non linear problem Actual Results: ° When activating nlpsolver, the error : "java.lang.reflect.InvocationTargetException" occur ° "Tools > solver..." doesn't work for optimising problems like minimising the sum of the square of differences, depending on two parameters. Expected Results: I would expect to have no error and to be able to sole a non linear problem Reproducible: Always User Profile Reset: No Additional Info: I can solve a non linear problem after removing "LanguageTool". As I already wrote, I'm not the only person concerned, c.f. https://code.google.com/archive/p/ooo2gd/issues/115 User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:54.0) Gecko/20100101 Firefox/54.0
I assume that you have also reported that on LanguageTool bug tracker (https://github.com/languagetool-org/languagetool/issues)?
By the way: where did you get the NLPSolver extension from? It is the part of LibreOffice since long ago. It should possibly be a part of some Ubuntu LibreOffice-related package (I'd assume that libreoffice-nlpsolver is the one).

Was Needinfo for a long time. Not clear if reported to LanguageTool. Feel free to set back to Unconfirmed should you experience with current versions and provide answers.
