JRE crashes during extraction of Maven index files in NetBeans 8.2

[Karl-Philipp Richter]

JRE crashes during extraction of Maven index files in NetBeans 8.2. I could reproduce this 4 times and it seems to happen permanently. The terminal contains

```

after the crash.

I submitted the bug report at the shown URL, but it's only an ivory tower internal bug tracker, so I can't access it anymore. It's missing the `hs_err_` and core dump, so it's useless anyway.
