Comments
a further comment on this at: https://bugs.eclipse.org/bugs/show_bug.cgi?id=439759 : "The problems seems to be that these jp2launcher.exe has not included the "visual style manifest" and therefore windows fall back to "Classic Mode". The javaw.exe has included the "visual style manifest". I also tried to add a jp2launcher.exe.manifest next to the jp2launcher.exe like described in the visual style guide but this doesn't fix it." and "According to the initial bug about using Visual Styles (https://bugs.eclipse.org/bugs/show_bug.cgi?id=45918 ) it was fixed in SWT this way: "We used activation contexts and embeded the manifest file in the DLL." So points to regression caused by new launcher code. - Should be able to test this by disabling secure launcher from deployment.properties. (deployment.security.use.insecure.launcher=true)
