New Fedora 21 release


Release Notes: http://docs.fedoraproject.org/en-US/Fedora/21/html/Release_Notes/

Download: https://getfedora.org/en/workstation/download/

Some changes/improvements I found interesting:

GNOME 3.14
Update GNOME to the latest upstream release, 3.14

GCC49
Switch GCC in Fedora 21 to 4.9.x, rebuild all packages with it.

Headless Java
Server installations of Fedora should usually not pull in packages related to X system or sound subsystem. For this reason part of OpenJDK package has been split into headless subpackage which has smaller dependency chain. Fedora packages should be migrated to require java-headless instead of full java package when appropriate

Java 8
Make Java 8 (provided by OpenJDK 8 which is java-1.8.0-openjdk) the default Java runtime. The current default Java runtime (Java 7, provided by OpenJDK 7, java-1.7.0-openjdk) will be obsoleted and removed.

    TableViewer.refresh(true, false) behaves as TableViewer.refresh(true, true)

    The problem I met is that refresh(true, false) method of org.eclipse.jface.viewers.TableViewer class behaves as refresh(true, true) on Linux platforms.

    I found an opened bug for this case: https://bugs.eclipse.org/bugs/show_bug.cgi?id=414455 but the current SWT 4.3 stable version doesn't contain the fix.

    To overcome this problem temporary (until SWT 4.4 is released) I used "SWT.MULTI" style bit during TableViewer creation.

    I played with different styles, but it is the only way to avoid the problem. "SWT.NONE" didn't help as well because of the logic inside org.eclipse.swt.widgets.Tablet constructor which overwrites "style" parameter:
