Re: [jdt-core-dev] Java9 Beta Branch

[Tom Schindl <tom.schindl@xxxxxxxxxxxxxxx>]

Hi,

Well the JDT-Patch is from "1.1.1.v20161221-1205_BETA_JAVA9" and
installed from http://download.eclipse.org/eclipse/updates/4.7-P-builds/
is there a location I can get a newer build from?

I only have Java9 b152 so there was no need to remove any other JREs.
