There is a newer version: 8.9.0.37768

According to the Java Language Specification: 

For compatibility with older versions of the Java SE platform,
the declaration of a method that returns an array is allowed to place (some or all of) the empty bracket pairs that form the declaration of the array type after the formal parameter list.
This obsolescent syntax should not be used in new code.


Noncompliant Code Example
public int getVector()[] { /* ... */ }    // Noncompliant

public int[] getMatrix()[] { /* ... */ }  // Noncompliant


Compliant Solution
public int[] getVector() { /* ... */ }

public int[][] getMatrix() { /* ... */ }
