"Mockito is a fantastic mock library for Java. I’m fascinated by how easy it is to use, compared to other things out there both in the Java and .NET world. Here is everything you need to know to get started in six really easy examples."

A couple of months ago we ran a survey asking a few questions about Java EE development, containers and redeploy times. Now that over 1100 people have responded it’s time to update the results. Since we’ve had more time to analyze them we also hope to provide a few insights into the data including a more detailed container breakdown.

So, as we all know, GWT hosted mode on the Mac with OS X Leopard didn’t work with Java 6 because Java 6 on the Mac was 64 bit only and the libraries used for hosted mode were 32 bit. You’d get java.lang.UnsatisfiedLinkError. The workaround was to use Java 5 for hosted mode. The release of Snow Leopard put paid to this scheme. In Snow Leopard you only have Java 6. A look at the installed Java versions shows 1.5 has been replaced by a link to CurrentJDK and CurrentJDK is 1.6.

The new Android 1.5 Early Look SDK is out since a few weeks. The "Android 1.5 highlights" page does not mention one highlight, which IMHO will become very important for all developers on the Android platform because it allows you to find memory leaks easily and analyze the memory usage of your Android applications.

I'm talking about the hprof-conv tool that allows you to convert an Android/Dalvik heap dump into an .hprof heap dump. The tool does not preserve all the information, because Dalvik has some unique features such as cross-process data sharing, that are not available in a "standard" JVM. Still the .hprof file is a good starting point and can be read with the Eclipse Memory Analyzer, which will interpret it like a normal file from a Sun 32 bit JVM. In the future it should also be not that difficult to read the Dalvik heap dump format directly and provide more information for memory analysis, such as which objects are shared and also maybe how much memory is used by native Objects (haven't checked that).

Don't get me wrong - I've written tons of Java over the last decade or so & think its been a great evolutionary step from C++ and Smalltalk (lots of other languages have helped too like JavaScript, Ruby, Groovy, Python etc). However I've long wanted a long term replacement to javac. I even created a language to scratch this itch.
