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) { }
