Suspicious ternary operator in varargs method call

Reports vararg method calls that use a ternary operator with mixed array and non-array branches.

When compiled, both branches are wrapped in arrays. As a result, the array branch is turned into a two-dimensional array, which may indicate a problem.

The quick-fix wraps the non-array branch in an array to prevent the compiler from doing the conversion.

Example:

static void bar(boolean flag) {
    Object[] a = {1, 2};
    Object b = "hello";
    foo(flag ? a : b);
}
static void foo(Object... obj) {
}

After the quick-fix:

static void bar(boolean flag) {
    Object[] a = {1, 2};
    Object b = "hello";
    foo(flag ? a : new Object[]{b});
}
static void foo(Object... obj) {
}
