Most objects referred-to by static variables will never be garbage collected. To be garbage collected, the class containing the static variable needs to get unloaded. That will only happen when its class loader gets garbage collected.
If the class was loaded by the system class loader (i.e. off the classpath), it will never be garbage collected, because the system class loader is never garbage collected.
