Edwin updated CXF-6245:
-----------------------
Description:
We have an application with quite a few jars in the classpath. Since the class
org.apache.cxf.xmlbeans.XmlBeansWrapperHelper doesn't exist, the loading of
this class causes the class loader to search the entire classpath which means
scanning each and every jar. This is causing performance issues for us where
under heavy load several threads get blocked while one thread is searching all
the jars in the classpath.
Here is the thread which is searching the classpath:
