[jbosstools-dev] Detecting a jboss 7.1 server startup

[phantomjinx]

Hi Max,

No. I wrote it like that just to define the difference between the IDE
and the application that is loaded to test my developement.

Looking at it again this morning, this may be the case. I think that I
am blocking the UI thread when the jboss worker threads need to display
the dialog for accessing the eclipse secure storage. Think I need to
move my content provider updates off the UI thread then update the tree
when the call is complete.

Mostly, they are 7.7.1 but some of the ide.eclipse plugins I have
brought into my workspace from svn trunk.

Thanks for getting back to me.

Cheers
