Known Issues - Java 9 and missing binaries in 3.1.3

With the latest release of Java 9 and IceLink 3.1.3, we are seeing access violations occurring in the libyuv JNI library when attempting to convert RGB image formats (and their endian, alpha variants) to i420. This conversion is required prior to encoding video frames. We are actively investigating this issue. An example of the crash and the corresponding stack trace is below for reference.
