I have not heard reports from Engineering or QA on testing with Java 8. I am downloading and will try, which I expect will work. It is unlikely that Wowza will utilize new features of Java 8 for general purposes because there is a business requirement for Wowza Engine to work on Java 1.6.
I am experiencing some problems with Oracle Java 1.8 (I tried both jre 1.8u5 and u20): After I start a stream (for example with the "Test Player"-Feature of the Engine Manager) it will play only for about 10sec. Then it freezes and it is not possible to start another one. Wowza is stuck - the cpu-usage of the wowza java thread goes up to 100% and if I try to restart the Engine it ends with "Killing process (20664) which didn't stop after 20 seconds"...
This happens on my testserver which is located in a VMware virtual machine. The specs of the VM are: SLES 11 SP3, 2GB Ram/1 core, Wowza 4.0.6 with Dev Licence, Java Max Heap Size 793MB
Everything works fine with IBM Java 1.6.0 and Oracle Java 1.7.0_55. Wowzastreamingengine_error.log reports nothing.
As we have to upgrade our live server to Java 1.8 due to the end of support of Java 1.7 it´s quite important to solve this problem.
