Changeset 12219 in josm for trunk/src

Timestamp:

Author:

Message:

see #14652 - ask Windows/macOS users to update their version of Java when it expires (i.e when the built-in JRE expiration date is passed, about 4 months after release, 1 month after Java should have asked to update by itself). It currently proposes to update all versions of Java 8 up to update 121, released on January 17, 2017, as its expiration date is May 18, 2017.
