Tag cvm-8.0.1, cvm-8.0.0 also have the same problem

[duanyangjing]

Problem lies in the system property java.vm.name.

cvm now returns OpenJDK 64-Bit Server VM (CompoundVM 8.0.1), which does not match the regex required in cvm/jdk8u/test/jtreg-ext/requires/VMProps.java

Looks like we need to change the jdk8u source code, wait for this patch first: #49
