Hi,
I have a persistent issue with Eclipse Kepler + latest ADT
(22.6.0.v201402070614-preview-1012920, but I don't think this is specific
to the latest version).
I have a rather large Android project using many Android libraries and Java
dependencies.
On a fresh launch of Eclipse, repeated building and launching on device
works fine and is reasonably fast for a while.
Building takes 10-30s.
After maybe a few hours, a launch on device trigerring a build remain stuck
on "Refreshing workspace" for several minutes (about 8 minutes),
then the build finally completes and the app starts on the device.
During these 8 minutes, taking thread dumps at regular interval shows that
Dex is running and doing stuff (not blocked aiting for something) but
abnormally slow.
For example 2 dumps of the thread it is running, at a few minutes interval,
taken with jvisualvm:
"Worker-46" prio=6 tid=0x000000000f766000 nid=0x15f8 runnable
[0x00000000230bd000]

The dumps are always different (executing Dex), proving that Dexing is in
process, except that it takes forever.
Always using jvisualvm to inspect Eclipse, it shows that plenty of memory
is available, both for the Heap and Permgen.
But of course, less is available than on a fresh start.
This issue is really bugging me as I'm forced to restart Eclipse every few
hours.
As a side note, I have quite a bit of plugins loaded in Eclipse and a large
workspace of projects of various nature.
The project I'm building has a total of 63 pre-dexed jars in total (some of
them just a few KB).
If there is something I can do to gather more info, please let me know.
