SystemStackError is untestable
------------------------------
Key: JRUBY-1354
URL: http://jira.codehaus.org/browse/JRUBY-1354
Project: JRuby
Issue Type: Bug
Components: Miscellaneous
Reporter: Charles Oliver Nutter
Assignee: Charles Oliver Nutter
There are a number of tests in our test suites that attempt to cause a
SystemStackError. Unfortunately, it seems this may be impossible to safely
recover from. Because a Java stack overflow could happen at any time, it's
always possible that a lock was about to be released, a preX or postX method in
ThreadContext has only partially completed, and so on. Because of this, stack
errors are going to almost always be fatal. Having them as part of the test run
causes intermittent inconsistent state in the runtime, which is the source of
our occasional test run failures in rubicon/test_array and bfts/test_array.
Because it's currently impossible to safely recover from a stack error I'm
disabling those tests. This bug will remain open until such time as stack
errors can be generated and handled safely.
