`UnnecessaryVarargsArrayCreation` false positive when an ambiguity is possible

[volodya-lombrozo]

Consider the following expression (constructor):

new ElegantObject(
    "fibonacci",
    new String[]{
        "+package org.eolang.examples",
        "+architect yegor256@gmail.com",
        "",
        "# This is the main abstract object that",
        "# represents n-th Fibonacci number",
        "[n] > fibonacci",
        "  if. > @",
        "    lt.",
        "      n",
        
        "    n",
        "    plus.",
        "      ^.fibonacci",
        "        n.minus 1",
        "      ^.fibonacci",
        "        n.minus 2",
    }
)

qulice complaints on it with the following error:

[INFO] PMD: src/test/java/integration/JarIT.java[98-126]: Unnecessary explicit array creation for varargs method call (UnnecessaryVarargsArrayCreation)

because the ElegantObject has the following constructor:

private ElegantObject(final String file, final String... content) {
    this.file = file;
    this.content = String.join("\n", content);
}

That said, we can't just remove new String[]:

new ElegantObject(
    "fibonacci",
    "+package org.eolang.examples",
    "+architect yegor256@gmail.com",
    "",
    "# This is the main abstract object that",
    "# represents n-th Fibonacci number",
    "[n] > fibonacci",
    "  if. > @",
    "    lt.",
    "      n",
    "      2",
    "    n",
    "    plus.",
    "      ^.fibonacci",
    "        n.minus 1",
    "      ^.fibonacci",
    "        n.minus 2"
)

It's impossible, because we will get a compiler error as the following one:

The constructor JarIT.ElegantObject(String[]) is am

Expected behaviour:

qulice doesn't complain on methods where it's impossible to replace array creation with varags.
