10 years ago Are you sure that you are using Java 1.7 ? Because the exception says something about "1.6.0_65" and the bug you're mentioning here is only known for java 1.6
What is "mvn -version" saying?

I use the "git clone https://github.com/stratosphere/stratosphere.git" command, and then I use "mvn clean package -DskipTests" to compile but it goes wrong. My java compiler version is javac 1.7.0_55. The error message is follow:
[INFO] --- maven-compiler-plugin:3.1:compile (default-compile) @ stratosphere-java --- [INFO] Changes detected - recompiling the module!
