[jbosstools-issues] [JBoss JIRA] (JBIDE-19773) Can Central tell the user what's wrong if gtk/swt/webkit not available so they know what to do?

Konstantin Marmalyukov commented on JBIDE-19773:
------------------------------------------------

To know which browser is currently used we should parse userAgent string with javascript. Here is userAgent string examples which is returned by SWT browsers:
* Lunix
** webkit : Mozilla/5.0 (Macintosh; Intel Mac OS X) AppleWebKit/538.1 (KHTML, like Gecko) Safari/538.1
** embedded XulRunner(v1.9) : Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.19pre) Gecko
** XulRunner24 : Mozilla/5.0 (X11; Linux x86_64; rv:24.0) Gecko/ /24.0
** XulRunner10 : Mozilla/5.0 (X11; Linux x86_64; rv:10.0.4) Gecko/ /10.0.4
* Windows
** IE : Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko

To make this detection possible we need to include SWT which comes with Eclipse 4.5 RC1 because of [this bug|https://bugs.eclipse.org/bugs/show_bug.cgi?id=465757]. [~mickael_istria], [~nickboldt], will we have Mars RC1 bundles in target platform for Beta2 release? If not, we can create browser function for detecting browser, but this is not very good solution.

> It was suggested today on build.next call by Max that it would be great if when gtk/swt/browser/webkit problems occur as a result of Central loading that we could notify the user what when wrong and suggest a solution.
