svn commit: r1825818 - in /poi/trunk/src/ooxml/testcases/org/apache/poi/openxml4j/util: ./ TestZipSecureFile.java

[ce...@apache.org]

Author: centic
Date: Sun Mar  4 13:33:38 2018
New Revision: 1825818

URL: http://svn.apache.org/viewvc?rev=1825818&view=rev
Log:
Add unit test which verifies that ThresholdInputStream can be used. This currently fails with Java 10 because the reflection relies on internals of class ZipFile that were changed.
