It appears that log streaming is no longer functional with the latest Cloud Foundry update to Pivotal Web Services (PWS). 

It seems that it is up to CF clients, so in this case the v1 CF Java client used by CFT, to use a new endpoint to obtain log streaming.

When testing on a JEE Neon.1, and deploying Dynamic Web project to PWS, the following error is encountered with CFT 1.0.1 release, and no log streaming occurs:
