[Jflex-devel] Minimum build JDK: 6->7 ?

[Steve R. <sa...@gm...>]

Hi Gerwin,

I’m working on adding Unicode 9.0 support to JFlex, and I noticed that my Maven version (3.3.9) no longer supports Java 6, which is documented as JFlex's minimum supported build version.

When the Travis build for the Add_Unicode-9.0 branch failed <https://travis-ci.org/jflex-de/jflex/builds/201132195>, I noticed that it’s configured to use Java 8.  The docs say that Java 6 is not supported - from <https://docs.travis-ci.com/user/ci-environment/>:

> Sun/Oracle JDK 6 is not provided because it reached End of Life in fall 2012.

On the Add_Unicode-9.0 branch I reconfigured Travis to use Java 7, which stopped the ccl-pre testsuite test from failing (the jflex output differed under Java8). 

I think we should switch the minimum supported build JDK for JFlex from 1.6 to 1.7.
