Mark Wielaard: New GPG key.
Finally created a new GPG key using gnupg. The old one was a DSA/1024 bits one and 8 years old. The new one is a RSA/2048 bits one. I will use the new one in the future to sign any release tarballs I might create. pub 2048R/57816A6A 2011-01-29 Key f...

Glassfish SecurityManager.checkPermission
After configuring Hudson to run in a Glassfish with security manager enabled I started to have problems in other applications, specially web applications using reflection to access private fields in Java classes. Over the web I noticed a lot of people struggling with the same issue (Seam, GWT, Vaadin, etc). The problem is caused because most of the modern frameworks tries to access Java private fields directly - perhaps motivated by the popularity of type-unsafe languages or just designed for better performance. The frameworks designer expect to have this freedom but the Security Manager imposes strict rules against that. Applications based on these frameworks running on a secure Glassfish will eventually throw an exception like:
java.security.AccessControlException: access denied (java.lang.reflect.ReflectPermission suppressAccessChecks)
at java.security.AccessControlContext.checkPermission(AccessControlContext.java:323)
at java.security.AccessController.checkPermission(AccessController.java:546)
at java.lang.SecurityManager.checkPermission(SecurityManager.java:532)
