As I reported in bug 152222, starting from comment #28, I was suffering unneccessary redeployments. Since I was thinking that the recent JDK/JRE-Upgrade solved the issue, it actually did not. But now I am definetely sure what causes the problem: If "Action Items" is opened, it seems that the files get scanned completely and somehow cause a refresh leading to a redeployment.
I can confirm this issue for NB7.2 (Win 7 x86_64), NB7.2.1 (MacOS Lion) and now also NB7.3 (Win 7 x86_64).
I will put Petr Jiricka in CC. Since I know the reason for the problem now, I's not urgent for me. But maybe other users are suffering the same problem and simply don't know what's happening.
Added Petr to CC
Assigning to the deployment infrastructure.
I think redeployment is triggered by CoS listener. Honzo is it possible? Can you suppress it?
Are there some simple steps for me to follow? I may be able to infer that from other locations, but having something readily available would make it easier and quicker.
Report from old NetBeans version. Due to code changes since it was reported likely not reproducible now. Feel free to reopen if happens in 8.0.2 or 8.1.
