Paul Rogers updated DRILL-5157:
-------------------------------
Description:
Run the {{TestDrillbitResilience.doMemoryLeaksWhenCancelled}} unit test. It
fails with the following stack trace and the memory leak trace shown second.
Strangely, this error appears only if the test is run as part of the overall
suite. The error does not appear if the test is run individually in the
debugger. This suggests that the problem described here is a side-effect of a
problem created by an earlier test.
Investigation (see notes below) reveal that this is a Maven dependency
management problem.
Stack trace that seems to show that the code was trying to find a Snappy native
library:
