java.lang.AbstractMethodError: com.sun.jna.Structure.getFieldOrder()Ljava/util/List;
comming out of the scope of org.netbeans.api.project.ui.OpenProjects init

please evaluate
Comment 4 Jaroslav Havlin 2014-08-15 08:29:04 UTC 
It seems that this problem has two possible causes:

1) Update of development version (using menu Tools -> Plugins -> Updates)
   - The change in one of the libraries in not compatible
     with some modules.
   - Please download the latest development build and reinstall the IDE.

2) Unsupported version of JNA library is in the class path
   - Remove the library, e.g. delete or move the JAR file, or use
     different JDK. The path of the library is usually
     C:\Program Files\Java\jdk{version}\jre\lib\ext\jna-{version}.jar
   - See bug 246033.

Thank you for reporting.
