Unnecessary apache commons-io dependency in spring-batch-test module [BATCH-2698]

[spring-projects-issues]

Mahmoud Ben Hassine opened BATCH-2698 and commented

The only usage of apache commons io library in spring-batch-test module is in DataSourceInitializer:

scripts = StringUtils.delimitedListToStringArray(stripComments(IOUtils.readLines(scriptResource
							.getInputStream(), "UTF-8")), ";");

Now that v4 is based on Java 8, IOUtils.readLines can be replaced with Files.lines and the dependency to commons io can be removed.
