OpenJDK 64-Bit Server VM warning: increase O_BUFLEN in ostream.hpp -- output truncated

[Thomas Stüfe]

Hi Andrew,

This would increase stack requirements in error situations, especially when
secondary signals occur during error reporting. Also, I think, there would
be no safe value to use, because classpath can be arbitrarily long?

I think in this case, printing code should be corrected.

Regards, Thomas
