[Bug] SniperJavaPrettyPrinter - Invalid ouput on annotated default method

[plcarmel]

Given the following input:

package org.example;

interface Example {

    @Deprecated
    default void doNotUseMePlease() {}

}

When performing a transformation on the class (changing the method name to "potato", for example) and pretty printing the model using SniperJavaPrettyPrinter, the annotation "@deprecated" and the "default" keyword end-up merged together.

package org.example;

interface Example {

    @Deprecateddefault void potato() {}

}

Code to reproduce the bug is available on GitHub:
