It appears there is more to the fix than a simple 393dc18 (not reproducible locally).

(hopefully) Fixed in 0.9.6.

Verified using the same Travis CI configuration as in eed3si9n/sbt (wip/discover-java-home) (build succeeded 10 times out of 10).

@eed3si9n please let me know if you experience any problems. 🙇‍♂️

@eed3si9n sorry for all the back and forth but do you think you could try

• jabba 0.10.0 (goroutine performing the installation is now locked to a single OS thread. Normally, this should not be required, but as I'm unable to reproduce the problem myself (tried both locally and on Travis CI (including the same docker image)) I can only guess at this point)
• switching from "Container on EC2" to "Virtual machine on GCE" (https://docs.travis-ci.com/user/reference/overview/#Virtualisation-Environment-vs-Operating-System)

[eed3si9n]

The previous failures may be been related to my Travis CI cache.

I saw your message above, and added a new commit on sbt to use 0.10.0, and it failed on the first try:

But it came to me that I might be causing this problem by caching

cache:
  directories:
    - $HOME/.ivy2/cache
    - $HOME/.sbt/boot
    - $HOME/.jabba

so I wiped out Travis CI cache, and it seemed to have worked:

Right... cache must have contained files without write permission (e.g. 0444) from jabba pre-0.9.5 (jabba 0.9.5+ makes sure write flag is set, but if the file (w/o write bit) already exists open(2) fails). This (along with incorrect install-check fixed in 0.10.1) explains everything.

Thank you for helping gunning these bugs down!
🙇‍♂️

Nice. Thanks for following up on all the loose ends.
