We've been using Lightstreamer for Java for many years. We are building new Linux servers with 7.1.2, and are getting this error on startup.
I can't find this class in the distributed Lightstreamer jars. Can someone help me find the right jar? Googling didn't help.

The MetadataControlListener class was introduced in Lightstreamer Server version 7.1.0 (as part of the java in-process SDK version 7.2.0).
However, since Lightstreamer Server version 7.1.2, the jar that contains this class has changed place.
Up to 7.1.1 it was Lightstreamer/lib/ls-adapter-interface.jar
From 7.1.2, that library (now part of the java in-process SDK version 7.3.0, which has become open-source) is now included as Lightstreamer/lib/adapters/ls-adapter-inprocess-7.3.0.jar
The launch scripts in Lightstreamer/bin/unix-like have changed to add it to the classpath.
Perhaps you expected fewer changes in this upgrade and are still using the previous launch script?
