+    # Compile BerkeleyDB's Java bindings with Java 1.5 as this is the
+    # oldest version of Java that the bindings are known to compile
+    # with.  This is done because ports that depend upon db46-java may
+    # be compiled with Apache Ant and Ant explicitly sets JAVA_HOME to
+    # /System/Library/Frameworks/JavaVM.framework/Home if JAVA_HOME is
+    # not already set.  If Oracle's JDK 7 is installed on the Mac and
+    # is set as the default Java version, then when BerkeleyDB's Java
+    # bindings are compiled the *.class files will be a newer format
+    # then the older Java in $JAVA_HOME can read.  So just compile
+    # BerkeleyDB with the oldest version of Java that can compile it.
+    # There is no harm in doing so as at application run time newer
+    # JVMs can read older class files and optimize them as if they
+    # were compiled with a newer version of Java.  The only
+    # performance loss may be a slightly longer class loading time,
+    # which is optimized in newer versions of Java.
