Trouble building 3.15

[Matt Barron]

Hi,
I am fairly new to building POI, but I have set up all of the dependencies
on my machine and I have yet to have it build successfully.  So I am just
looking for some pointers to get it kicked off.

Build environment information:
     [echo] Using Ant: Apache Ant(TM) version 1.9.7 compiled on April 9
2016 from /home/matt/build_tools/apache-ant-1.9.7, Ant detected Java 1.8
(may be different than actual Java sometimes...)
     [echo] Using Java: 1.8.0_101/1.8.0_101-b13/25.101-b13/OpenJDK 64-Bit
Server VM from Oracle Corporation on Linux: 4.7.0-1-default
     [echo] Using Findbugs: 3.0.1 for Java 1.8.0_101


The compile target runs with no issue, but the test target fails with the
following message under test-ooxml:
[junit] Running org.apache.poi.xssf.streaming.TestSXSSFSheetAutoSizeColumn
    [junit] Tests run: 26, Failures: 1, Errors: 0, Skipped: 0, Time
elapsed: 0.149 sec

BUILD FAILED
/home/matt/javaLibraries/apache-poi/trunk/build.xml:1443: The following
error occurred while executing this line:
/home/matt/javaLibraries/apache-poi/trunk/build.xml:1396: Tests failed

If I run the jar target, it similarly fails under compile-ooxml-lite with
the following message:
     [java] Time: 113.927
     [java] There was 1 failure:

Thanks in advance,
