OpenJDK and Bug-fixes

AdoptOpenJDK as Astah's JRE

Due to Oracle's end of public support of Java8 for commercial users, we've changed the bundled JRE for Astah to AdoptOpenJDK.
If your company security policy does not allow a use of app with un-supported JRE, update to version 8.1, then you will be all set.

  • [7410] We switched bundled JRE from Oracle Java to AdoptOpenJDK.

    We've changed a drawing library with this version, so diagrams created with earlier version may look different on Ver8.1. This [Update Diagram] menu adjusts the difference to make the diagram look better.
