Diwaker Gupta created JCLOUDS-181:
-------------------------------------
Summary: Blobstores that lack proper support for 100-Continue
don't work with JDK7
Key: JCLOUDS-181
URL: https://issues.apache.org/jira/browse/JCLOUDS-181
Project: jclouds
Issue Type: Bug
Components: jclouds-blobstore
Affects Versions: 1.6.1
Reporter: Diwaker Gupta
jclouds added the "Expect: 100-Continue" to the putBlob API for most blobstores
sometime back. Handling of 100-continue differs between JDK6 and JDK7 in that
unlike JDK6, JDK7 will expect a response from the server and will only time out
IF a read timeout has been set on the underlying HTTP connection [1].
As a result, if applications set Constants.PROPERTY_SO_TIMEOUT and use a
blobstore that doesn't properly support the Expect header (i.e., doesn't
respond with 100-Continue) on JDK7, the putBlob operation will essentially hang
forever.
Specifically, both HPCS and Google Cloud Storage are impacted by this.
