            Bug ID: 114056
           Summary: Extensions "nlpsolvert.oxt" and "LanguageTool-x-x.oxt"
                    are incompatible
                    "java.lang.reflect.InvocationTargetException"
           Product: LibreOffice
           Version: 5.1.6.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: bgork at juggling.ch

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.

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.
