David Capwell created CASSANDRA-16003:
-----------------------------------------
Summary: ToolRunner added in CASSANDRA-15942 isn't portable
Key: CASSANDRA-16003
URL: https://issues.apache.org/jira/browse/CASSANDRA-16003
Project: Cassandra
Issue Type: Bug
Components: Test/unit
Reporter: David Capwell
The JVM will output to stderr on some environments to show what flags that were
picked up, when this happens all tests which validate stderr start to fail.
This was found in the org.apache.cassandra.tools.ClearSnapshotTest as it
switched to use the ToolRunner; below is a sample failure on my laptop (I had
to modify the asserts since they don’t include the input)
{code}
java.lang.AssertionError:
Expecting empty but was:<"Picked up _JAVA_OPTIONS:
-Djava.net.preferIPv4Stack=true
">
at
org.apache.cassandra.tools.ToolRunner.assertEmptyStdErr(ToolRunner.java:339)
at
org.apache.cassandra.tools.ToolRunner.waitAndAssertOnCleanExit(ToolRunner.java:334)
at
org.apache.cassandra.tools.ClearSnapshotTest.testClearSnapshot_RemoveMultiple(ClearSnapshotTest.java:91)
{code}
Here _JAVA_OPTIONS is used globally on my system so fails the test; there is
also JAVA_TOOL_RUNNER which is used the same way.
