Bug#858876: libjna-jni: causes NoClassDefFoundError

[YOSHINO Yoshihito]

Package: libjna-jni
Version: 4.2.2-2
Severity: grave
Justification: renders package unusable

Dear Maintainer,

netbeans with native look and feel enabled fails to look up libjnidispatch.so:

  INFO [org.netbeans.core.nativeaccess.NativeWindowSystemImpl]
  java.lang.NoClassDefFoundError: Could not initialize class com.sun.jna.Native
          at com.sun.jna.platform.unix.X11.<clinit>(X11.java:380)
          at com.sun.jna.platform.WindowUtils$X11WindowUtils.getAlphaVisualIDs(WindowUtils.java:1537)
          at com.sun.jna.platform.WindowUtils$X11WindowUtils.isWindowAlphaSupported(WindowUtils.java:1487)
  [catch] at com.sun.jna.platform.WindowUtils.isWindowAlphaSupported(WindowUtils.java:1823)
          at org.netbeans.core.nativeaccess.NativeWindowSystemImpl.isWindowAlphaSupported(Unknown
Source)
          at org.netbeans.core.windows.FloatingWindowTransparencyManager$1.run(Unknown
Source)
          at java.lang.Thread.run(Thread.java:745)

This is apparently caused by a change introduced in 4.2.2-1:

>  * Renamed the native library to avoid conflicts with other JNA jars used
>    on the system (LP: #1065253)

Workaround: Creating a symlink libjnidispatch.so -> libjnidispatch.system.so
fixes this error.
