> currently to determine which exact java is being used by the CassandraDaemon jvm could be difficult. Some may have use rpm/deb java package, other may have used tarbar and set JAVA_HOME, PATH, etc etc.
> It "could be" done, but may take some iteration to get the true answer if one's setup is complicated (user is root/cassandra and contains difference env settings between cassandra startup user vs the login user)
> It would be very helpful to have this information simply logged in the log file, right at the beginning. This helps identifying the java type/version quickly without much operation overhead, and easily done in 1-liner:
> logger.info("Java vendor/version: {}/{}", System.getProperty("java.vm.name"), System.getProperty("java.version") );
> In OpenJDK java, you will something similar to:
> INFO [main] 2011-06-22 07:08:16,610 AbstractCassandraDaemon.java (line 95) Java vendor/version: OpenJDK 64-Bit Server VM/1.6.0_20
> In Java(TM), you will get something like:
> INFO [main] 2011-06-22 00:15:34,936 AbstractCassandraDaemon.java (line 96) Java vendor/version: Java HotSpot(TM) 64-Bit Server VM/1.6.0_24
> this little edition will go a long way.
