A file created from template and its reformat being done in EDT. The repository updater is busy with html.validator first time initialisation. There's a separate issue for that validator slowness, but seems like a problem in the wizard's code doing the reformat in EDT.
This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.
Thanks for your cooperation,
NetBeans IDE 8.2 Release Boss
