    [ https://issues.apache.org/jira/browse/HDFS-4013?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13473696#comment-13473696

Trevor Robinson commented on HDFS-4013:
---------------------------------------

I just hit this with the Oracle 1.6.0_35 JVM (64-bit), running on a 3.3 GHz Sandy Bridge and
not in a VM (i.e. "fast"):

{noformat}
Running org.apache.hadoop.hdfs.TestHftpURLTimeouts
Tests run: 2, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.62 sec <<< FAILURE!
testHsftpSocketTimeout(org.apache.hadoop.hdfs.TestHftpURLTimeouts)  Time elapsed: 552 sec
 <<< ERROR!
java.lang.NullPointerException
        at org.apache.hadoop.hdfs.TestHftpURLTimeouts.checkConnectTimeout(TestHftpURLTimeouts.java:122)
        at org.apache.hadoop.hdfs.TestHftpURLTimeouts.testHsftpSocketTimeout(TestHftpURLTimeouts.java:100)
{noformat}

Note that the second "Time elapsed" message appears to be bogus; the test failed immediately,
presumably within 0.62 seconds.

Some runs also fail like this (when {{!ignoreReadTimeout}}):

> The case fails at line 116, where message is null. I guess this may be an openjdk-specific
behavior, but it would be nice to have it fixed although openjdk is not officially supported.
> FYI: The exception is thrown with null message at java.net.SocksSocketImpl.
