    [ https://issues.apache.org/jira/browse/SHIRO-545?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15270294#comment-15270294 ] 

Harry Metske commented on SHIRO-545:
------------------------------------

This also breaks the shiro tools hasher:

{noformat}
java -jar ~/shiro-tools-hasher-1.2.4-cli.jar -p

Error: Password hashing (prompt without echo) uses the java.io.Console to read passwords safely.  This is only available on Java 1.6 platforms and later.

Specify -d or --debug for more information.

> If Shiro is running in Java 8 it assumes that the major version is 1.3, because this case it's not included in the if blocks and goes to the default version which is 1.3, also the " if (version.indexOf("1.7.") != -1) {" should be contains, instead of indexOf, contains is highly more readable, so the code should be something like
