InputStreamReader failed on 2k boundary

Both on Solaris and Win32 platform, InputStreamReader throws an exception
during compilation of source on which a Japanese Kanji (or multibyte character) exists over the 2k boundary (i.e. first byte of Kanji is at byte 2047, and second
byte of Kanji is at byte 2048), java.io.InputStreamReader malfunctions.
That makes compilation of some java sources fail.

Solaris ouputs:
