If a Date column is indicated as a primary key in a service.xml, generated files will compile incorrectly.
Steps to reproduce
1. Create a lrsb directory in liferay-source/modules
2. Add both the lrsb-api and lrsb-service folders from zip to the lrsb directory
3. Run "gradle buildService" in lrsb. Observe no code changes.
4. Run "gradle compileJava" in lrsb. Ensure compilation.
1. No code changes from service builder
2. lrsb module compiles correctly
1. "java.util.Date" import is removed from Foo.java
2. lrsb does not compile.
