Development

Hi,

I’m under debian 7
using netbeans in java

my dependencies are

       <dependency>
        <groupId>org.languagetool</groupId>
        <artifactId>languagetool-core</artifactId>  
        <version>3.6</version>
    </dependency>

    <dependency>
        <groupId>org.languagetool</groupId>
        <artifactId>language-all</artifactId>
        <version>3.6</version>
    </dependency>

my code

JLanguageTool langTool = new JLanguageTool(new French());
List matches = langTool.check(“je suis un texte”);

I have this error

What’s the output of java -version? I assume LT runs for you outside the development environment?

oups

debian x64

openjdk version “1.8.0_72-internal”

4

Could you try if using Oracle JDK makes a difference?

5

I’ve just tested on windows 10 x64
java version “1.8.0_121”

the cause might be openjdk

Can I run it under openjdk ?

6

I’ve compiled the same code under debian and jdk 1.8
It’s working.

But the problem is that we are working with openjdk.

is there a way to make it work with it ?

I just tried running LT in IntelliJ using OpenJDK 1.8.0_121 (the one that comes with Ubuntu 16.04) and it worked for me.
