title: "A JNI Error has occurred" for one instance of the program, not for another
body: <p>I made a large program in Eclipse Java Mars on one computer which worked fine. I exported the program as a runable Jar-file and running it gave no problem whatsoever. Even when I exported the entire project to another computer, the program still works. </p>
  
  <p>The issue came forth on the other computer when I made minor changes to the project. These changes were only content based changes and should make no difference on the functionality of the program. <strong>Running the program from eclipse appears to have no problems.</strong> However, when I want to run the newly created Jar-file I get the following error:</p>
  
  <pre><code>Error: A JNI error has occurred, please check your installation and try again. 
  </code></pre>
  
  <p>followed by a frame saying:</p>
  
  <pre><code>A Java Exception has occurred. 
  </code></pre>
  
  <p>So my question is: </p>
  
  <p><strong>How is it possible that a different instances of the same program cannot run via a Jar-file, while the older instance can?</strong></p>
  
  <p>I used the same JDK version (1.8.0_73) on both computers, and installed them in pretty much the same way: I first installed Java together with NetBeans via a combined release. Following, I installed Eclipse. The only difference is that on the new computer I installed eclipse offline, i.e. without the Eclipse installer </p>
