+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.
