RFR: 8375013: J2DdemoTest.java - Platform default encoding used for process output

[ANUPAM DEV]

Hi,

new String(b, 0, n) looks at the operating system's default locale. If these differ between the build machine and the test runner, tests can fail.
StandardCharsets.UTF_8 is guaranteed to be available on all Java platforms.

Since "ERROR" and "Exception" are ASCII characters, and ASCII is a subset of UTF-8, this will correctly match the tokens regardless of the underlying platform's obscure defaults.

Kindly review.

Regards,
Anupam
