Subject: [PATCH] Add ExceptionUtilsGenerator.java.

A gradle task (in gradle/utils.gradle) is normally used to generate an
ExceptionUtils class. Since gradle depends on groovy, we cannot use it, so
we copy the code from the gradle task to a new file. Running this file then
generates the required class.
