Subject [jira] [Commented] (CASSANDRA-9416) 3.x should refuse to start on JVM_VERSION < 1.8
Date Sat, 23 May 2015 17:09:17 GMT


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!

> When I was looking at CASSANDRA-9408, I noticed that {{conf/}} and {{conf/cassandra-env.ps1}}
do JVM version checking and should get updated for 3.x to refuse to start with JVM_VERSION
< 1.8.
