We may attempt to use fast reflection (MethodHandle) to access to non-public constructor! Appears to be rather effortless:

' Notice that these quotation marks are unpaired (precisely the same character is employed as an opener and a closer), which is a hangover from the typewriter technological know-how which was the precursor of your earliest Personal computer enter and output products.

Incorrect quoting of nested strings can present a stability vulnerability. Utilization of untrusted data, as in data fields of an SQL question, ought to use prepared statements to circumvent a code injection assault.
