+* Fix https://issues.apache.org/bugzilla/show_bug.cgi?id=48903
+ and https://issues.apache.org/bugzilla/show_bug.cgi?id=48694#c8
+
+ Fix deadlock in WebappClassLoader, caused by Sun JDK ClassLoader
+ implementation. The cause is that JDK already holds a lock on ClassLoader
+ instance when calling our ClassLoader.loadClass() method, and thus trying
+ to use a different lock causes deadlocks. See
+ http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4670071
+
+ Add system property to enable use of JDK 7 API to register a class loader
+ as capable of parallel loading. This feature will be turned off by
+ default.
+
+ Also fixed synchronization issue in JasperLoader, where findClass()
+ method was called without proper synchronization.
+
+ FIXME: This patch has not been applied to trunk yet.
