jsp:include throws IllegalStateException in App Engine Managed VM Java runtime

[Etienne via StackOverflow]

With the new Managed VM environment I get an IllegalStateException whenever I do a jsp:include

java.lang.IllegalStateException
 at org.apache.jasper.runtime.ServletResponseWrapperInclude.getOutputStream(ServletResponseWrapperInclude.java:65)
 at javax.servlet.ServletResponseWrapper.getOutputStream(ServletResponseWrapper.java:94)
 at com.google.apphosting.vmruntime.CommitDelayingResponse.<init>(CommitDelayingResponse.java:62)

 at com.google.apphosting.vmruntime.jetty9.VmRuntimeWebAppContext.doScope(VmRuntimeWebAppContext.java:394)
...

I forked the hello app to show the error : https://github.com/erugeri/appengine-java-vm-hello/compare/jsp-include-bug?diff=unified
