Known Issues
------------

Version 1.2.0 is not compatible with Wowza 4.8.28.

When used with JDK 11.0.2 (e.g. Wowza Streaming Engine 4.8.18) then a [bug in the JDK](https://bugs.openjdk.java.net/browse/JDK-8220723)
can cause the below errors in the logs:

.. code-block::

    ERROR server comment - Raskenlund License Manager: Error communicating to the server: javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated:
    java.lang.RuntimeException: javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated|at com.raskenlund.wse.License.sendRequest(License.java:442)|

The current workaround is upgrading the JDK or adding an additional JVM argument ``-Djdk.tls.client.protocols=TLSv1.2``  to your
``startup.sh`` script:

.. code-block::

    %_EXESERVER% %_EXECJAVA% %WMSTUNE_OPTS% %JMXOPTIONS% -Djdk.tls.client.protocols=TLSv1.2 -Dcom.wowza.wms.runmode="%runmode%" -Dcom.wowza.wms.native.base="win" -Dlog4j.configurationFile="%WMSCONFIG_HOME%/conf/log4j2-config.xml" -Dcom.wowza.wms.ConfigURL="%WMSCONFIG_URL%" -cp %CLASSPATH% com.wowza.wms.bootstrap.Bootstrap start
