IntelliJ collapsing single line methods

Since I've updated my version of intelliJ (14.x to 15.x) it has started automatically collapsing single line methods in the Java editor:

Previous version:

public void setContext(SecurityContext context) {
    this.context = context;
}

Latest version:

public void setContext(SecurityContext context) { this.context = context; }

Is there a way to prevent this? I find the original version much easier on the eyes!

Thanks.

Open 'Settings' from the File menu. Under 'Editor' -> 'General' -> 'Code Folding', you will find a 'Collapse by Default' section.

Simply uncheck 'One-line methods' and click OK.
