OpenJDK versions 11.0.15+10, 17.0.3+7 introduced new functionality to allow Java to enable strict path checking. This included disallowing the use of : in any place other than directly after the drive letter. Unfortunately, this check had the side effect of breaking compatibility with special device paths, such as NUL:, which in turn, prevents Logstash from starting. This feature was gated by the use of the jdk.io.File.enableADS property with a value of true disabling the check. This property was introduced with the default value of false, which prevents logstash from starting in a Windows environment. While the next release is anticipated to set this value to true, this commit explicitly sets that value to enable Logstash to be able to start correctly. Relates: #14066
