Fix handling of URI query parameters

In this release, I added the ability to create URI objects with query parameters. These cannot be simply appended to the path component, because keys and values must be encoded, but the query lead character (?), param delimiters (&), and key/value delimiters (=) must not.

Add 'findExecutableOnSystemPath' method; eliminate Guava

In this release, I added a new findExecutableOnSystemPath function to the FileUtils class. This will eliminate reliance on similar Selenium APIs in Selenium Foundation.

I also removed dependencies on Guava APIs. These really weren't doing very much for me, and including this library could cause mixed-version issues for client projects.

NOTE: This is a breaking change, because the Params class has now switched from using the Guava Optional class to the standard Java Optional class.

Fix Macintosh path acquisition; omit duplicate entries; clean up stuff

In this release, I fixed a bug in the acquisition of Macintosh path entries, optimizing the process. I added logic to omit entries that were already represented. I also performed some basic clean-up - removing unnecessary boxing, adding 'final' specifiers where possible, etc.

PathUtils: Add methods to acquire system paths

In this release, I added methods to acquire the system paths in two different flavors - standard PATH from the system environment and the path_helper collection found on Mac OS X. These are returned independently as list augmenters or together as a path-delimited string.

Build for Java 8; upgrade dependencies and plugins

In this release, I finally dropped support for Java 7. By building this library for Java 8, I'm able to upgrade dependencies to newer versions that resolve identified vulnerabilities.

Add new stack trace capture class

In this release, I added a cool widget for capturing diagnostic information: the StackTrack class. This class extends Throwable and it's intended to facilitate capture of the flow of execution that triggered system state changes that may lead to future operation errors. For example, an object that's no longer valid might get used subsequent to the event that caused it to become invalid, or a long-lived object may get discarded without corresponding resources being cleaned up.

For more details, check out the blog post that provided the implementation for StackTrace.

Add new classpath/javaagent method that returns a list

In this release, I added a new getContextPaths method that returns the classpath and Java agent specifications in a list. After using the existing getClasspath method, I realized that I ended up having to perform a lot of processing on the string it returns that essentially undoes the string concatenation the method had just done.

Tweak dependencies to suppress aggressive Guava warning

Guava 30.1.1-android adds an obtrusive warning regarding the intent to remove support for Java 7 in an unspecified future release. I figured out a way to suppress the warning, but this requires pulling in guava transitively through guava-agent:

com.nordstrom.tools:guava-agent:30.1.1a
└── com.google.guava:guava:30.1.1-android

Upgrade dependencies and plugins

This release contains no functional changes but is instead focused on project housekeeping.
I also fixed a platform-specific bug in one of the unit tests and resolves a JavaDoc warning.

Revise cross-compile configuration

This release is solely focused on non-functional aspects of the project, Specifically, I revised the POM to use the cross-compilation features that were added in Java 9. This eliminated the need for maven-toolchains-plugin, which obviated the Eclipse M2E lifecycle-mapping configuration. I also migrated the project to the newer Sonatype s01 staging host for the deployment of releases.

In addition to this project configuration refresh, I corrected the formatting of line breaks in my JavaDoc comments.
