[jbosstools-issues] [JBoss JIRA] (JBIDE-17496) Central installation fails if done right after Eclipse start

[Martin Malina (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-17496?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12973203#comment-12973203 ] 

Martin Malina commented on JBIDE-17496:
---------------------------------------

I tried this in master.
Before applying the PR, I couldn't really get the NPEs, but I got all the other errors.

After applying the PR (using p2 director, on an archived fresh install of JBT), when I tried to reproduce the issue, I was shown a progress bar and the install dialog only showed up once it was ready. The delay was quite long, but it might be because of my poor internet connection. The install then worked fine. On Eclipse restart, this went much faster.

On another attempt (again, extracted from an archive), I tried waiting for a bit before installing anything - the status bar didn't show any action anymore. And when I tried to install FindBugs, it still took perhaps 5 sec waiting, even though I thought it was already done. I wish it was faster. But anyway, it worked.

So +1 for the PR.

> When you try to install something from Central as soon as JBDS starts for the first time, you can get errors.
> I can reproduce some sort of errors every time (I tried 4 or 5 times), but only on a completely fresh install of JBDS/JBT (no central repo data cached).
> It looks like there is a race condition.
> Several times when I tried to install Findbugs, I got:
> {quote}
> The following connectors are not available: FindBugs
> Proceed with the installation anyways?
> {quote}
> Followed by the Computing connector errors with NPEs familiar from JBIDE-17471 
> !connector-error.png!
> If I proceed anyway, the install dialog is empty.
> If I click that I don't want to install, I get this:
> {code}
> Problems occurred while performing installation: The following connectors are not available: FindBugs (id=edu.umd.cs.findbugs.plugin.eclipse.feature.group, site=https://devstudio.jboss.com/updates/8.0-staging/central/core/)
> The following connectors are not available: FindBugs (id=edu.umd.cs.findbugs.plugin.eclipse.feature.group, site=https://devstudio.jboss.com/updates/8.0-staging/central/core/)
> {code}
