Eclipse shows empty error message with Java 9

Question

I have installed the Java 9 plugin. My project hasn't changed, but when I try to run, I get this:

Answer 1

Seems like a configuration issue as per my understanding. There are two possible causes/solution to it:

1. From the logs:

   Root exception:
   java.lang.ExceptionInInitializerError
       at com.jniwrapper.util.ProcessorInfo.b(SourceFile:95)
   Caused by: com.jniwrapper.LibraryNotFoundException: Cannot find JNIWrapper native library (jniwrap64.dll) in java.library.path:
   

   Eclipse is not able to configure the java.library.path properly, in which case you can try setting the VM argument using the following on the command line:

   -Djava.library.path="${workspace_loc:project}\lib;${env_var:PATH}"
   

   Check out How to add native library to "java.library.path" with Eclipse launch (instead of overriding it) for further details and platform specific solutions.

   && make sure you include the path to jdk-9 early access build that should ideally be a must for the plugin used based out of Java9.

2. Also, the log reads

   !ENTRY org.eclipse.ui 4 0 2017-08-27 09:22:31.358
   !MESSAGE Unhandled event loop exception
   !STACK 0
   java.lang.ArrayIndexOutOfBoundsException: -1
       at es.org.chemi.games.snake.ui.GameField.createGameField(GameField.java:217)
       at es.org.chemi.games.snake.ui.GameField$1.controlResized(GameField.java:99)
       at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:236)
       at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:86)

       at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1079)
   

   For the pertaining code, you might want to look into the implementation of createGameField at GameField.java:217. If this wasn't specifically occurring on previous java version for you then solving (1) should get rid of this or else you might want to give the solutions at Eclipse Bug: Unhandled event loop exception No more handles a try.
