That might be a sign of undesirable behavior in invokeMatchingMethod() that is too dependent upon the order of methods given to it.Īs you mention, type hinting is good for avoiding the significant performance hit of reflection.

Java(TM) SE Runtime Environment (build 1.6.0_39-b04) getMethods() returns the 4 /abs methods in different orders on Java 6 and 7, causing invokeMatchingMethod() to pick a different one on the two JVMs: In Reflector.java method invokeStaticMethod(Class c, String methodName, Object(link: ) args) there is a call to getMethods() followed by a call to invokeMatchingMethod().

Thilo at 11:21 Add a comment 1 Answer Sorted by: 1 The Java updates for OS X come from Apple, not Oracle (that 'owns' Java and provides downloads for Windows and Linux). La versin de Apple de Java para OS X ahora solo est disponible como una descarga opcional a travs de la compaa. 1 If such an update exists, you would get it via System Update.

It will not be activated by default on Safari (but double check to be sure) or any other browser. I do not know what is the precise difference between Java 6 and Java 7 that leads to this behavior difference, but this is some evidence that this has something to do with Java 6 vs. If you want to run Java Software, just go to Oracle, download the Runtime environment and run your Java program. However, I tried two Java 7 JVMs, and it gave the following behavior which looks closer to what you would hope for. Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode) Java(TM) SE Runtime Environment (build 1.6.0_45-b06) OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode) You can download the Mac OS X JDK and JRE from Java SE Downloads page. OpenJDK Runtime Environment (IcedTea6 1.12.5) (6b27-1.12.5-0ubuntu0.12.04.1) This release includes fully supported JRE for Mac OS X 10.8.3 (Mountain Lion) and above.
