Hello,
we are using RAP 1.5.2 for about 7 applications among 400 customers. Most
of them still stick to Windows XP and therefore to IE 8 (because our
customers are mostly bank institutes who depend on external IT service
provider).
Recently a security vulnerability in the Microsoft VML-Library came up
which was fixed by an out-of-band patch (
http://support.microsoft.com/kb/2964358 relating to
https://technet.microsoft.com/de-de/library/security/ms14-021).
Instead of using this patch the service provider of our customers
suggested disabling the VML-capabilities of IE by unregistering the dll
"%CommonProgramFiles%\Microsoft Shared\VGX\vgx.dll". This makes every
RAP-application non-functional on IE < 9, because it tries to initialize
an org.eclipse.rwt.VML in org.eclipse.rwt.GraphicsUtil, if the engine
reports to support VML [1].
As far as we can see, IE up to version 8 reports as engine name "mshtml",
which in org.eclipse.rwt.Client leads to returning true in function
supportsVml. [2]
So the question is: Is it possible to get around this with
a) not having the customers upgrade to IE >= 9
b) not having the customers use a different browser
c) not having the customers to re-enable the vgx.dll
?
Best regards
Frank Jakop
