Hi Thomas,

OK, but I have no idea what you mean by "printing code should be corrected". Sure, it should be corrected, but do do what? It seems a bit lame that debugging printf can't print long strings.

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

"/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.
