>
> Key: NETBEANS-963
> URL: https://issues.apache.org/jira/browse/NETBEANS-963
> Project: NetBeans
> Issue Type: Bug
> Components: debugger - Java
> Affects Versions: 9.0
> Environment: Linux; Release Build 316
> Reporter: Peter Nabbefeld
> Priority: Critical
>
> When I've selected the "String Value" column in Variables view of the Java debugger, the following exception is thrown even if I just move the cursor over the string value.
> This does only happen for object values; primitive values do not seem to be affected.
> Probably it's related to tooltips, as those are shown for primitive values, while object values throw an exception.
> As this makes it impossible to show and review large strings and thus makes debugging harder, I've set the status to "Blocker".
