I'm seeing the same problem. I am not able to upload any generated
GWT .cache.html files to the server.
The upload is working fine when I remove all .cache.html but failed on
any .cache.html file. The generated GWT file size is about 450 Kb. The
previous GWT version file was possible to upload the file size was
about the same. I updated GWT 1.7 to 2.0 and implemented some logic
changes but without big API changes so HashMap with Serializable
solution will not work for me.
It looks like there is some datastorage issue on App Engine servers.
Small files update is working fine but any big file update is failed
with exception
