--------------------------------------
https://github.com/apache/jclouds/pull/64
> JClouds is not using the JDK's KeepAliveCache when
> UntrustedSSLContextSupplier is used
> --------------------------------------------------------------------------------------
>
> Key: JCLOUDS-1520
> URL: https://issues.apache.org/jira/browse/JCLOUDS-1520
> Project: jclouds
> Issue Type: Bug
> Components: jclouds-core
> Affects Versions: 2.1.0
> Reporter: Roded Bahat
> Priority: Major
> Fix For: 2.3.0, 2.2.1
>
> Attachments: screenshot-1.png
>
> Time Spent: 1h 50m
> Remaining Estimate: 0h
>
> It seems like the fact that {{UntrustedSSLContextSupplier}} returns a new
> {{SSLContext}} on every {{get()}} call causes a consistent cache miss on the
> JVM's {{sun.net.www.http.KeepAliveCache}} which causes JClouds to not reuse
> existing TLS connections even though it could.
> The cache miss happens at {{sun.net.www.protocol.https.HttpsClient}} line 329
> (openjdk version "1.8.0_222"):
> {noformat}
> /* see if one's already around */
> ret = (HttpsClient) kac.get(url, sf);
> {noformat}
> To reproduce, consider the following main:
> {noformat}
> public static void main(String[] args) {
> Properties overrides = new Properties();
> overrides.setProperty(org.jclouds.Constants.PROPERTY_TRUST_ALL_CERTS,
> "true");
> BlobStoreContext blobStoreContext =
> ContextBuilder.newBuilder("aws-s3")
> .endpoint("https://s3.amazonaws.com";)
> .credentials("...", "...")
> .overrides(overrides)
> .buildView(BlobStoreContext.class);
> BlobStore blobStore = blobStoreContext.getBlobStore();
> blobStore.getBlob("roded-data", "blobname");
> blobStore.getBlob("roded-data", "blobname");
> blobStore.getBlob("roded-data", "blobname");
> blobStoreContext.close();
> System.exit(0);
> }
> {noformat}
> If run using a JUL logging.properties with the following logger set to FINEST:
