title: ZipException in Eclipse thrown all the time
body: <p>Since this morning (i've updated some plugins, and updated mac os X) I get a ZipException, any time the system wants to read a jar/zip file. At first I thought it was a bug in the new version of the plugin, but it seems to be pretty low level, in the native java.util.zip.Zipfile.open(..) method.</p>
  
  <pre><code>Error: Caused by: java.util.zip.ZipException: error in opening zip file
  at java.util.zip.ZipFile.open(Native Method)
  at java.util.zip.ZipFile.&lt;init&gt;(ZipFile.java:127)
  at java.util.jar.JarFile.&lt;init&gt;(JarFile.java:135)
  at java.util.jar.JarFile.&lt;init&gt;(JarFile.java:99)
  </code></pre>
  
  <p>Anyone have any idea where this comes from? Anyone experiencing the same problem? I am using Eclipse Galileo.</p>
  
  <p>My java -version says:</p>
  
  <pre><code>java version "1.6.0_24"
  Java(TM) SE Runtime Environment (build 1.6.0_24-b07-334-10M3326)
  Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02-334, mixed mode)
  </code></pre>
  
  <p>I've checked the dirs of the files that contain some of the jars that are being opened, for instance /System/Library/Java/Extensions/AppleScriptEngine.jar:</p>
  
  <pre><code>$&gt; ls -l
  -rwxrwxrwx  1 root  wheel     6470 Jan  6  2010 AppleScriptEngine.jar
  </code></pre>
  
  <p>It drives me crazy, cos a lot of plugins are now failing. Any hints are very very welcome!</p>
