The integer cache is well known for over 10 years, presently there is a JVM knob to make it larger: java.lang.Integer.IntegerCache.high So the solution is not surprising at all. Personally I'd just employ an enhancing classload and replace some of bytecodes ICONST_2 with ICONST_3. (one byte change in the bytecode). Yet, overall uninteresting question. |
