[SUREFIRE-2058] Corrupted STDOUT by directly writing to native stream in
forked JVM 1 with UTF-8 console logging (#518)
[SUREFIRE-2058] Corrupted STDOUT by directly writing to native stream in
forked JVM 1 with UTF-8 console logging
* [SUREFIRE-2058] Add readString unit test covering cases with overflowing
output buffer
- shouldReadStringOverflowOnNewLine - ends up with 1 single byte (LF)
remaining on input buffer
- shouldReadStringOverflowOn4BytesEncodedSymbol - causing an infinite loop
with 4 bytes left on input buffer
* [SUREFIRE-2058] Flip and clear output char buffer after each chunk read
Overflow can happen even when output buffer has still some remaining space
left
* [SUREFIRE-2058] Add static import for emptyMap and remove explicit type
arguments
