When using JDK 1.7, the Maven build fails, and reports an OutOfMemoryError. Example (Mac OS X 10.10):

$ export MAVEN_OPTS="-XX:MaxPermSize=512m -Xmx2g"
$ export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_17.jdk/Contents/Home
$ mvn clean install
...
Exception: java.lang.OutOfMemoryError thrown ...

Changing JAVA_HOME to use JDK 1.8 enables the build to succeed:

$ export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home
$ mvn clean install
...
[INFO] BUILD SUCCESS

I'm considering creating a pull request to add something like this under <plugins> in pom.xml, to make the JDK 1.8 requirement more explicit:

        <plugin>
            <artifactId>maven-enforcer-plugin</artifactId>
            <executions>
                <execution>
                    <id>enforce-java</id>
                    <goals>
                        <goal>enforce</goal>
                    </goals>
                    <configuration>
                        <rules>
                            <requireJavaVersion>
                                <version>[1.8,)</version>
                                <message>
                                    The hapi-fhir Maven build requires JDK version 1.8 or higher.

It does seem like at this point the build needs JDK1.8 to proceed. We're still maintaining support for JDK1.6 in the library, but requiring JDK 1.8 to build seems reasonable.

Pull request would certainly be accepted :)
