- * The class file definition (vmspec/2nd-edition) says:
+ * See http://en.wikipedia.org/wiki/Java_class_file for an up-to-date
+ * list of version numbers. Currently known (taken from that table) are:
*
- * "Implementations of version 1.2 of the
- * Java 2 platform can support class file
- * formats of versions in the range 45.0
- * through 46.0 inclusive."
- *
- * The class files generated by the build are currently
- * (as of 11/2006) reporting version 49.0 (0x31.0x00),
- * however, so we use that as our upper bound.
+ * J2SE 6.0 = 50 (0x32 hex),
+ * J2SE 5.0 = 49 (0x31 hex),
+ * JDK 1.4 = 48 (0x30 hex),
+ * JDK 1.3 = 47 (0x2F hex),
+ * JDK 1.2 = 46 (0x2E hex),
+ * JDK 1.1 = 45 (0x2D hex).
*
* Valid ranges are typically of the form
* "A.0 through B.C inclusive" where A <= B and C >= 0,
