Subject [jira] Commented: (DIRSTUDIO-436) Eclipse Hangs on Startup

-------------------------------------------

Hi Eric,

thanks for the thread dump. You are right, DirStudio causes the hang, see the snippet below.
When opening your XML file each XML-Editor is asked if it can handle the XML file. The ApacheDS
Configuration plugin then tries to parse the XML file and the parser tries to lookup the DTD
or schema that is defined in your XML file from internet. It seems you don't have internet
connection. We have to configure the XML parser to not download DTDs or XML schemas from internet.

You could try the following workarounds:
- Enable internet connection, specify a proxy within Eclipse if necessary
- If you don't use the "ApacheDS Configuration" plugin you could disable or uninstall it.

>                 URL: https://issues.apache.org/jira/browse/DIRSTUDIO-436
>             Project: Directory Studio
>          Issue Type: Bug
>    Affects Versions: 1.2.0, 1.3.0
>         Environment: Windows XP Pro
> Eclipse Ganymede
> Directory Studio 1.3
>            Reporter: Eric C
>
> Intermittent problem, seemingly dependent on what editor is open when eclipse is closed.

> If I have a .jsp open in an editor window (or .xml) and in focus, when restarting eclipse
it will hang.
> The workaround to this is to delete all the <editor>...</editor> elements
and their content from the workbench.xml eclipse file. If I have multiple editors open, sometimes
I have the patience to find the one that is causing the problem and just delete that element
from the workbench.xml.
> When I close Eclipse with a .java file open in an editor and in focus, I do not have
this problem.
> I have had this problem for months, and was having a bear of a time figuring out what
was causing this, and a teammate installed this plugin (at my behest, and later to my embarrassment)
and his Eclipse hung when restarting. I cleaned his workbench.xml of open editors and it came
up fine. He had installed 1.3, and had an xml file open at the time. I updated my version
to 1.3, and can still reproduce the hang by simply closing Eclipse with an open jsp file.
> I could probably produce a stack dump while hung if it would help, but I'm not proficient
enough with RCP to debug the problem myself.
