I have just found that the restlet library breaks down on a misformed header. When reading Now I think it is likely, that Expires: -1 is wrong, though I have not checked the specs. But is it reasonable for the at org.restlet.util.DateUtils$ImmutableDate.<init> (DateUtils.java:249) at org.restlet.util.DateUtils$ImmutableDate.valueOf (DateUtils.java:234) at org.restlet.resource.Variant.setExpirationDate (Variant.java:321) at com.noelios.restlet.http.HttpClientCall.getResponseEntity (HttpClientCall.java:251) at com.noelios.restlet.http.HttpClientConverter.commit (HttpClientConverter.java:110) at com.noelios.restlet.http.HttpClientHelper.handle (HttpClientHelper.java:79) at net.java.sommer.addressbook.AgentResourceObject$1 $1.cacheUrlToFile(AgentResourceObject.java:263) at net.java.sommer.addressbook.AgentResourceObject$1 $1.doInBackground(AgentResourceObject.java:177) at net.java.sommer.addressbook.AgentResourceObject$1 $1.doInBackground(AgentResourceObject.java:303) at java.util.concurrent.FutureTask$Sync.innerRun (FutureTask.java:269) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask (ThreadPoolExecutor.java:650) at java.util.concurrent.ThreadPoolExecutor$Worker.run (ThreadPoolExecutor.java:675)
