Created attachment 149205 [details] IDE log I'm not able to start NetBeans with latest promoted JDK9 build, it fails with java.lang.InternalError: Default flavor mapping not found See the attached log for details. Thanks NetBeans IDE Dev (Build 201409150001) (#2da6c79a156c) Linux version 3.13.0-32-generic running on i386 Java 1.9.0-ea; Java HotSpot(TM) Client VM 1.9.0-ea-b30; Oracle Corporation Java(TM) SE Runtime Environment 1.9.0-ea-b30
The same happens on Windows8. On first attempt, the IDE started OK though and it threw this error after I tried to use clipboard. I haven't been able to start it again since then (perhaps OS restart that would empty clipboard would help) NetBeans IDE Dev (Build 201409150001) (#2da6c79a156c) Windows 8 version 6.2 running on amd64 Java 1.9.0-ea; Java HotSpot(TM) 64-Bit Server VM 1.9.0-ea-b30; Oracle Corporation Java(TM) SE Runtime Environment 1.9.0-ea-b30
I think it is caused by "non empty" system clipboard. If clipboard is empty (e.g. after OS restart), IDE starts OK and seems to be without problem. If clipboard contains something, this error is thrown. If I use clipboard in e.g. browser while IDE is also running in background, the same error is immediately thrown in IDE even though it is not focused. Reassigning to JDK problems.
Stando, you had a look at clipboard stuff recently...
