 # Require

 This only works in JDK 8u76 and WITHOUT a security manager, because of `BadAttributeValueExpException` in here:

 https://github.com/JetBrains/jdk8u_jdk/commit/af2361ee2878302012214299036b3a8b4ed36974#diff-f89b1641c408b60efe29ee513b3d22ffR70

 And Please replace `coherence.jar` with your weblogic version, if not, you will get serialVersionUID inconsistent error.

 Only test on Centos jdk8u202 Weblogic 12.2.1.4.
