Right.

This may indicate some sort of compiler bug.  
`_ZN3org7eclipse3swt8internal8Callback4bindEJiPS3_PN4java4lang6ObjectEPNS6_6StringESA_ibbi', 
which is actually
org.eclipse.swt.internal.Callback.bind(org.eclipse.swt.internal.Callback, java.lang.Object, java.lang.String, java.lang.String, int, boolean, boolean, int)int
should be resolved internally by swt-win32.jar.
