Bug Fix(es):

• A defensive security change in an earlier OpenJDK update led to a performance degradation when using the Scanner class. This was due to the change being applied to many common cases that did not need this protection. With this update, we provide the original behaviour for these cases. (RHBZ#1862929)

Solution
