JPA 2.1 Entity Graph - Part 2: Define lazy/eager loading at runtime

This is my second post on Entity Graphs, one of the features introduced with JPA 2.1. The first post described the usage of named entity graphs. These can be used to define a graph of entities and/or attributes at compile time that shall be fetched with a find or query method. Dynamic entity graphs do to the same but in a dynamic way. This means you can use the EntityGraph API to define your entity graph at runtime.
If you have missed the first post and want to read how to define a named entity graph or how lazy loading issues were solved with JPA 2.0, check this post: JPA 2.1 Entity Graph - Part 1: Named entity graphs

Conference Report: JUG Saxony Day 2014

Last friday (2014-04-04) I visited the JUG Saxony Day 2014 in Dresden, Germany. It was the first event organized by the JUG Saxony and to make it short, it was great! The event was well organized and had lots of interesting talks.
But let's get into more details ...

The conference offered 4 tracks with 5 sessions each:

1. Software development process
2. Java technology
3. Research
4. Java mobile and enterprise applications with Java

So I had to make a hard decision to select 5 tracks for the day...
