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

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

I keep seeing this message:

OpenJDK 64-Bit Server VM warning: increase OBUFLEN in ostream.hpp -- output truncated It happens because classpath is this:

"/local/aarch64/dev/build/linux-aarch64-normal-server-slowdebug/jdk/modules/jdk.zipfs:/local/aarch64/dev/build/linux-aarch64-normal-server-slowdebug/jdk/modules/java.transaction:/local/aarch64/dev/build/linux-aarch64-normal-server-slowdebug/jdk/modules/java.desktop:/local/aarch64/dev/build/linux-aarch64-normal-serv..." 4533 characters long. It's because of modules. Should we increase OBUFLEN or remove the message? Andrew.
