Environment:this occurs with rare race conditions, and only when having an internet proxy user-password.
However, the performance problem is for all platforms
Description
cf https://bugs.eclipse.org/bugs/show_bug.cgi?id=452228
Eclipse UI is "dead-locking" itself at startup (but this is not detected as a real java object synchronization dead-lock), due to some race-condition with the "org.springframework.ide" plugins at startup.
It seems to be due to several errors dialog modal box simultaneously opened as modal windows, and the impossibility to close one or the other! None of the window can have focus to deblock the other!
the 2 modal dialog opened while starting eclipse are:
- an error message from one of the plugins installed, from sping-ide, showing me
title: Problem Occurred (Not Responding)
content:
'Initializing Bambo' has encountered a problem
An internal error has occured.
button <<ok>> <<details >> ... both disabled
window: impossible to obtain focus
- another modal dialog box for proxy authentication:
title: Password Required (Not Responding)
content:
Connect to my-proxy... .com
IAP Authentication - Please enter your internet User Name (firstname.lastname) and Password
User name: <input field>
button: <<OK>> <<Cancel>> .... both disabled
window: impossible to obtain focus
Internally, looking at a Full thread dump, you can see that org.springframework eclipse plugins is trying to do a remote HTTP call for getting some data through the P2 protocol, but it is doing the blocking call from the UI dispatch thread! Internally, eclipse has to do some internal workspace refresh and this is valid only from within a worker thread.
Also note that performing remote io blocking callsfrom the UI dispatch thread is a performance problem, annoying for the user because it degrades the responsiveness of the eclipse application.
A detailed analysis of the bug was posted to the eclipse bug tracking system
https://bugs.eclipse.org/bugs/show_bug.cgi?id=452228
However, the bug was simply closed on their side, pretending it was not due to eclipse, but to the external "org.springframework.ide" plugins.
I suggest that you simply use an asynchronous worker thread to perform HTTP P2 call outside of the UI dispatcher thread! Cf in
at line 179: StsProperties.readProperties() is doing a remote HTTP call
it is called from
org.springsource.ide.eclipse.dashboard.internal.ui.IIdeUiConstants.<clinit>(IIdeUiConstants.java:25)
at eclipse startup ... from the UI dispatch thread !
Here is an extract of the thread stack:

You you are curious to seehow it can really dead-lock eclipse at startup, here is the full thread stack
