[hibernate-dev] ArrayHelper cleanup

[Vlad Mihalcea]

Hi,

When reviewing this PR (
https://github.com/hibernate/hibernate-orm/pull/1305/files), I noticed that
some methods can be simply replaced by java.util.Arrays (e.g. indexOf,
toStringArray),
while other methods are not used at all (e.g. reverse).

Since this is an internal helper utility, do we want to clean it by
removing the unused/commented/redundant methods, or shall we leave it as is?
