The bad news: If I save my files the NetBeans IDE stops working without any reaction.
Comment 1 arittner 2014-09-23 19:37:02 UTC 
Tested it again, reproducible killing NetBeans with loosing my last changes.
Comment 2 arittner 2014-09-23 19:43:51 UTC 
Ok, found the "problem"

The correct use is Type<Type<String>[]> NOT Type<Type[]<String>>. It was a typo. But it should not kill the NetBeans IDE.
Comment 3 Martin Balin 2016-07-07 07:18:38 UTC 
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
