[Bug 1552764] [NEW] Eclipse is very slow/hangs on a fresh 16.04 install (gtk/swt issue?)

[Michael]

Public bug reported:

I installed a fresh Ubuntu 16.04 64 bit from nightly build (2016-03-02).

Eclipse Mars.2 (4.5.2) is often very slow / hangs, especially on start
of actions (searching projects, importing them, search for updates,
install plugins etc.

Things I tried:
  * openjdk8 /oracle java 8
  * OS / CS nvidia driver
  * unity / gnome (metacity and compizz)
  * fresh workspace

jvisualvm  shows that much cpu time is consumed by
rg.eclipse.swt.internal.gtk.OS._g_main_context_iteration[native] ...

** Affects: java-common (Ubuntu)
     Importance: Undecided
         Status: New


** Tags: eclipse gtk hang java swt

** Summary changed:

- Eclipse very slow on a fresh 16.04 install (gtk/swt issue?)
+ Eclipse is very slow/hangs on a fresh 16.04 install (gtk/swt issue?)
