I had the same issue and What I did to solve it:

1. Install a proper JDK version

[https://www.wowza.com/docs/manually-install-and-troubleshoot-java-on-wowza-streaming-engine](https://www.wowza.com/docs/manually-install-and-troubleshoot-java-on-wowza-streaming-engine)

ex) Wowza Engine 4.7.8 -\> JDK 9.0.4

1. eclipse: Right-click on your project and select

`"Properties -> Java Compiler"`, check **“Enable project specific settings”** and select the same JDK Version from the **“Compiler compliance settings”** select box.

1. eclipse: Under `Window -> Preferences -> Java -> Compiler`, set Compiler compliance level to the same JDK Version.
