I have released a new preview version created from java9 branch.
It can run under jre9 under linux and windows.
Because mac java api has changed in jdk9 in a non backward compatible way jre8 is embedded in mac distribution.
To test java9 in eclipse you need the latest eclipse (oxygen) with java 9 support installed from the marketplace.
If there are no related bug reports I shall merge branch java9 into branch 1.6.x soon.
