Michael Shuler commented on CASSANDRA-9416:
-------------------------------------------
There was a java7 feature that we required 1.7u25 or higher in cassandra-2.0.
Unless there is some feature Cassandra is using that was added in patch level
u45, no, it would not be correct to depend on u45 or higher. I think a check of
1.8 is sufficient, unless someone knows of a particular java8 feature that is
being used from a particular patch level. For instance, trunk currently builds
and runs tests fine for me on 1.8u5. [~rogercafe] if you could update the patch
for just a 1.8 check, I think that's fine for now. Thanks!
> 3.x should refuse to start on JVM_VERSION < 1.8
