Java 7: A complete invokedynamic example

Another blog entry in my current Java 7 series. This time it's dealing with invokedynamic, a new bytecode instruction on the JVM for method invocation. The invokedynamic instruction allows dynamic linkage between a call site and the receiver of the call. That means you can link the class that is performing a method call to the class (and method) that is receiving the call at run-time. All the other JVM bytecode instructions for method invocation, like invokevirtual, hard-wire the target type information into your compilation, i.e. into your class file. Let's look at an example.

Customizing Parameter Names When Binding Spring MVC Command Objects

With http parameter names, there is no way to customize them, which is odd, since this is meta-data, and it should be configurable using annotations. If you need to customize them (for example, for SEO reasons), you can plug some little pieces of code and Spring MVC will let you do it

Modeling, with Tools/Without

Got all the way to downloading the trial version when I saw that it was an exe. Yes, folks, Windows only.. in 2012. Unbelievable. Hilarious that these guys are selling tools for doing MDA. Guys, where is your PIM? Oh, yeah, you don‘t have one (clearly). Your codebase is already a PSM (platform-specific model).

Unreachable Catch Block - A Most Unobvious Bug

Earlier today I was working on some HTTP comms code adding a few changes, which are of no consequence here. One of the things that the code did was to read data from a server and, if the read failed, then it re-newed the connection and retried the read. The code ran something like this:

Search Needs to Help Disprove Patent Trolls

There’s not really a setting in a search engine to make a disproving search versus a finding search. If there was, then many patent trolls would be uttering a long bellow of anguish and going back under the bridges where they were hiding.
