The solution is to update the jsp-impl.jar library file since GlassFish 3.0.1 used an older and buggy one.

Download the newest jsp-impl.jar from http://download.java.net/maven/2/org/glassfish/web/jsp-impl/
(currently the newest version is 2.2.2-b03)

Overwrite the file in ${GLASSFISH_HOME}/glassfish/modules/jsp-impl.jar with the new jsp-impl.jar (rename the file to omit the version number).

Now your Java EE applications should run just fine. I also run a mixed Java EE/Scala web application and it runs fine with the new jsp-impl.jar.
