Zardoz89 opened a new pull request #3: Fix pdfbox 4671
URL: https://github.com/apache/pdfbox-jbig2/pull/3
 
 
   Fixes https://issues.apache.org/jira/browse/PDFBOX-4671
   
   Keeps being necessary to use [TwelveMomkeys Listener](https://github.com/haraldk/TwelveMonkeys#deploying-the-plugins-in-a-web-app), but removes the random NoClassDefFoundError when the plugin it's running inside of a servlet container.
   
   Why was this happening ?
   
   Because the java service registry is "VM global", it doesn't by default work well with servlet contexts. Servlet contexts dynamically loads and unloads classes (using a new class loader per context). If you restart your application, old classes will by default remain in memory forever. If a read is attempted using one of the remaining "old" Logger or Cache, weird exceptions (like NullPointerExceptions when accessing static final initialized fields or NoClassDefFoundErrors for uninitialized inner classes) may occur.
