+/**
+ * This class is used to wrap the IntelliJ ant logger in order to provide more meaningful
+ * output when building langtools. The basic ant output in IntelliJ can be quite cumbersome to
+ * work with, as it provides two separate views: (i) a tree view, which is good to display build task
+ * in a hierarchical fashion as they are processed; and a (ii) plain text view, which gives you
+ * the full ant output. The main problem is that javac-related messages are buried into the
+ * ant output (which is made very verbose by IntelliJ in order to support the tree view). It is
+ * not easy to figure out which node to expand in order to see the error message; switching
+ * to plain text doesn't help either, as now the output is totally flat.
+ *
+ * This logger class removes a lot of verbosity from the IntelliJ ant logger by not propagating
+ * all the events to the IntelliJ's logger. In addition, certain events are handled in a custom
+ * fashion, to generate better output during the build.
