Stephan Ewen commented on FLINK-2464: ------------------------------------- I have seen a similar failure as well. It seems very strange, because that check means that for a buffer, the first 57 bytes are as expected and the 58th is unexpected. And the length is correct as well. I have no idea how that could happen... > BufferSpillerTest sometimes fails > --------------------------------- > > Key: FLINK-2464 > URL: https://issues.apache.org/jira/browse/FLINK-2464 > Project: Flink > Issue Type: Bug > Components: Streaming > Reporter: Gyula Fora > Priority: Minor > > The BufferSpillerTest failed with the following error: > org.apache.flink.streaming.runtime.io.BufferSpillerTest > testSpillWhileReading(org.apache.flink.streaming.runtime.io.BufferSpillerTest) > Time elapsed: 3.28 sec <<< FAILURE! > java.lang.AssertionError: wrong buffer contents expected:<0> but was:<58> > at org.junit.Assert.fail(Assert.java:88) > at org.junit.Assert.failNotEquals(Assert.java:743) > at org.junit.Assert.assertEquals(Assert.java:118) > at org.junit.Assert.assertEquals(Assert.java:555) > at > org.apache.flink.streaming.runtime.io.BufferSpillerTest.validateBuffer(BufferSpillerTest.java:290) > at > org.apache.flink.streaming.runtime.io.BufferSpillerTest.access$200(BufferSpillerTest.java:42) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
