When generating an update center in  a new module suite, NetBeans puts out an incorrect combination of layer/bundle files, which causes an exception to be thrown in the IDE if the update center is loaded. I am attaching a module suite with only one module (an update center). 

Even if the layer file does have a correct solution, the wizard should not, by default generate code that does not work.

The offending line of code in the layer file is as follows:

<attr name="displayName" bundlevalue="org.suite.test.Bundle#Services/AutoupdateType/org_suite_test_update_center.instance"/>

This value used to be generated like so:

<attr name="SystemFileSystem.localizingBundle" stringvalue="org.suite.test.Bundle"/>

However, this no longer works correctly either, as this causes NetBeans to correctly load in the module, but incorrectly remove the update center if the module is uninstalled. At least, however, in this case, it works and does not throw an exception on load.

Here is the exception thrown now when the wizard generates the update center layer.xml file (on bootup):
