Subject [jira] Commented: (MATH-173) One-way ANOVA
Date Fri, 11 Jan 2008 07:32:34 GMT

    [ https://issues.apache.org/jira/browse/MATH-173?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12557925#action_12557925

Simon Kitching commented on MATH-173:
-------------------------------------

Re compatibility with java 1.3: 

The javac compiler option -source (presumably same as ant.build.javac.source) just ensures
that no *language features* beyond the specified version are used, eg autoboxing or 'for (String
x:arrayOfStrings)' or annotations. But it does NOT check whether you are using apis that did
not exist in the runtime lib for the specified version.

The -target option (presumably ant.build.javac.target) just ensures that the generated bytecode
format is compatible with the specified target version.

In order to check whether code is compatible with version x, you really need to compile against
the runtime libraries for version x; it should be possible to compile with java1.5 but using
the libs from 1.3 for example. But in practice just using java1.3 is probably easier.
