Removing unused imports leaves extra blank line after package statement, isn't idempotent #598
Description
I have a class that if I format it twice with google java formatter it will produce 2 different results. This is not what I would expect - I would think that you can format a file any number of times and google java formatter should always produce the exact same result. Is my assumption wrong ?
Here is an example:
original class:
$ cat inital_class.java
package com.sun.something;
import com.x;
import com.y;
import com.z;
public class MockedLiveServiceExecutionContext {
}
$
If I then format it I get this:
$ java -jar ./google-java-format-1.9-all-deps.jar --replace inital_class.java
$ cat inital_class.java
package com.sun.something;
public class MockedLiveServiceExecutionContext {}
$ cat inital_class.java | cksum
42955951 79
$
And if I format it again I get this (it's removed an extra space):
$ java -jar ./google-java-format-1.9-all-deps.jar --replace inital_class.java
$ cat inital_class.java
package com.sun.something;
public class MockedLiveServiceExecutionContext {}
$ cat inital_class.java | cksum
