[Wtp-wst-dev] Re: [atf-dev] Mozilla Error on Linux

[Robert Goodman <goodmanr@xxxxxxxxxx>]

Moved the bug to ATF while we investigate
a solution. It looks like the Welcome page is a browser control On Linux
this causes SWT to do its initialization code in Mozilla.java before ATF
can set the path to XULRunner. The initialization code in Mozilla.java
is only executed once per workspace start. The problem doesn't occur on
sequential workspace starts since the welcome page doesn't show up. 

    Thanks
      Bob

Subject	[atf-dev] Mozilla Error on Linux

Hi,
    I don't know if this is a correct list. But I found a SWT
bug using 
the ATF plug-in.
    We are working on Linux RedHat Enterprise 4. We install the
ATF 
Plug-in like as said in the ATF's page. But in first time we try to run
the Mozilla Browser in a new workspace we found a NullPointerException.
The bug occurs when the ATF Plug-ins requires the SWT  Mozilla Broswer,
in the org.eclipse.swt.browser.Mozilla.getWebBrowser(Mozilla.java:1258),
in the first time that I tried to open a mozilla for a workspace, this
method throw the InvocationTargetException. When I restart the Eclipse
and try to open a Mozilla browser again everything works fine.
    I looked for this bug in the WST Bugzilla, but I found nothing
like 
this. I don't know if this is a ATF bug, so I create a new SWT Bug : 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=201774
    Sorry this is the incorrect list....

Thanks,
Victor Osório
