Hi Édouard, We have the GAE driver that used to work, but that was more about configuring a single-threaded executor and some other http related stuff.
As far as I know, the GAE support has been untested for several releases, as I believe the community is not using it, but it is good to have a real use case! I haven't seen reflection restrictions before, but I'm not a GAE user, so I don't know the details and its limitations. Looking at the stacktrace, it seems that the failure happens when trying to build the deserialization context. jclouds uses Gson to deserialize the API responses, and it uses reflection to make sure it will be able to build the corresponding Java object, by making all the constructors accessible. This seems to be not allowed in GAE, and we could try to configure the GAE module to "disable" that reflection, and use only the visible constructor. However, this has been out there since 2013 and I'm not sure if working only with the visible constructors would be compatible with the current domain model of all providers. In any case, it is worth giving it a try. Mind opening a JIRA [1] issue so we can properly track this? Thanks! I.
