Description

I am having problems building the latest master with Java 6. I tried building the whole project

mvn clean install -DskipTests

and I also tried building individual modules

mvn --projects parquet-common -am -amd -U clean install -DskipTests

Both fail with the same error shown below. SemanticVersion class uses Integer.compare(int,int) which was introduced in Java 1.7, but, AFAIK and according to the pom file (and to PARQUET-146) Parquet should still be built using Java 6. Similarly TestInputOutputFormatWithPadding and TestInputOutputFormat classes depend on java.nio.file package that was introduced in Java 1.7

When I switch over to Java 7 the build succeeds.
