Same here. Can confirm this issue as far back as nightly 2018-10-26. Could also be earlier, but I noticed it for the first time at that point. Crashes also via usage by the VSCode plugin, effectively breaking the usage for any projects depending on nightly.

@lweberk crashes in the Eclipse Corrosion plugin too.

2018-10-20 doesn't suffer from this, but has other regressions
2018-10-17 is the most recent nightly I can actually work with

Still open as for 2018-11-06
