Levin Messing created NETBEANS-2709:
---------------------------------------
Summary: NullPointerException on trying to open Java Platforms
Key: NETBEANS-2709
URL: https://issues.apache.org/jira/browse/NETBEANS-2709
Project: NetBeans
Issue Type: Bug
Components: java - Platform
Affects Versions: 11.0
Environment: Product Version: Apache NetBeans IDE 11.0 (Build
incubator-netbeans-release-404-on-20190319)
Java: 12.0.1; Java HotSpot(TM) 64-Bit Server VM 12.0.1+12
Runtime: Java(TM) SE Runtime Environment 12.0.1+12
System: Windows 10 version 10.0 running on amd64; Cp1252; de_DE (nb)
Reporter: Levin Messing
I tried to set "[https://docs.oracle.com/en/java/javase/12/docs/api/]"; in Java
Platforms in Javadoc. (I do not know if it was this exact link)
I closed Java Platforms and then tried to open it again, but it did not open
and the NullPointerException occurred.
Deleting my config folder under AppData\Roaming\NetBeans fixed this issue.
I was not able to reproduce this error. But the exception may help to find this
Bug.
