Let's Code Jumi #351: NIO.2 Migration (Part 1)
Java 7 comes with a new file I/O API (NIO.2), which has numerous improvements over java.io.File. Upgrading to the new API is best done in small steps, the same way as when refactoring to remove primitive obsession.

Let's Code Jumi #350: Java 7 Language Level
It turns out that changing a project's language level is not as simple as it seems. Changing Maven's settings on a per-module basis is easy, but IntelliJ IDEA 11 doesn't support compiling multiple modules with mixed language levels (IIRC, newer IDEA versions do support it).

Let's Code Jumi #347: Bytecode Assertions (Part 1)
A too high Java class file version can break its consumers, so it's worth writing a test for. At the same time we can make it easier to write assertions for all class files in a JAR file.

Let's Code Jumi #344: Generic Properties (Part 1)
Refactoring towards a generic way of representing DaemonConfiguration's bean properties, to convert them to and from system properties.

Let's Code Jumi #343: Phase Change Pattern
I invented a design pattern which makes it easy to update immutable objects without language support, by providing a way to make an object immutable and back again mutable.

Let's Code Jumi #341: Unit Tests (Part 1)
I have a bunch of ideas how to still refactor the daemon and suite configuration classes, but a prerequisite for quick refactoring is good unit test coverage.

Let's Code Jumi #338: Daemon Configuration (Part 1)
The SuiteConfiguration class is a bit non-cohesive, because it holds also daemon-related parameters which are used differently from suite-related parameters.

Let's Code Jumi #335: Suite Configuration (Part 1)
To avoid changing JumiLauncher always when new suite parameters are added, the current approach needs to be refactored.
