instead of comparing string, I think it makes it cleaner to directly parse the property as boolean, using Boolean.parseBoolean(System.getProperty(SWT_AUTOSCALE_DISABLE_COMPATIBILITY_CHECK))

[HeikoKlare]

Indeed. It usually makes sense to use System.getProperty() when you want to allow that no value for the property needs to be specified to enable it, e.g., -Dswt.autoScale.force without =true. Then you can do something like

Object disableCompatibilityCheck = System.getProperty(SWT_AUTOSCALE_DISABLE_COMPATIBILITY_CHECK);
if (disableCompatibilityCheck  != null && !"false".equalsIgnoreCase(disableCompatibilityCheck) { 
... 
}
