Recently I encountered similar error [1] but 2.0.0-SNAPSHOT jar fixed it for me. You can follow the email thread for more information. It also mentions what could have possibly fixed it in 2.0.0-SNAPSHOT.

I am using jclouds (2.0.0-snapshot) and tried to get KeyPairApi using the following code: try { Optional<KeyPairApi> keyapi = api.getKeyPairApi(region); KeyPairApi keyPairApi = keyapi.get(); } catch (Exception e) { LOGGER.error(e); } The following error occurs: java.lang.IllegalStateException: Optional.get() cannot be called on an absent value But the codes works for Openstack Kilo. Any help would be greatly appreciated Best regards, -- Kai Liu Ph.D. student Department of Geography and GeoInformation Science George Mason University
