Hello Mark,
I get this sometimes too on the GAE/J developmenr web server after the
next web page has been served. I do not find this exception to be
reliably reproducible: sometimes it happens, usually is doesn't.
I am running GAE/J 1.4.2 with the JDK 1.6.0_24 for Microsoft Windows
XP.
An example of my errors are:
org.apache.wicket.WicketRuntimeException: Unable to write the
response
at org.apache.wicket.Response.handleException(Response.java:286)
at org.apache.wicket.Response.write(Response.java:310)
...
Caused by: java.io.IOException: Closed
at org.mortbay.jetty.AbstractGenerator
$Output.write(AbstractGenerator.java:629)
at org.mortbay.jetty.AbstractGenerator
$Output.write(AbstractGenerator.java:579)
at org.apache.wicket.util.io.Streams.copy(Streams.java:159)
at org.apache.wicket.util.io.Streams.copy(Streams.java:126)
at org.apache.wicket.Response.write(Response.java:306)
... 32 more
This is followed immediately by what you get:
java.lang.IllegalStateException: STREAM
at org.mortbay.jetty.Response.getWriter(Response.java:616)
