mbien opened a new pull request, #7586:
URL: https://github.com/apache/netbeans/pull/7586
When the last local maven repo scan didn't clean up properly, for example
when the JVM exits during scan, subsequent scans would throw
`java.io.IOException: Cannot create temporary directory`.
This has a fairly low probability since local index scans finish fast - saw
this during debugging.
exception:
```
java.io.IOException: Cannot create temporary directory:

```
how to simulate:
create a `tmp-local` folder in your fresh cache folder, trigger initial
local repo indexing, e.g by adding a dependency to a maven project.
