7.4.5 -XX:[+|-]JavaLogAsynchronous
-XX:[+|-]JavaLogAsynchronous specifies whether to enable the asynchronous output functionality for log files.
Description
-XX:[+|-]JavaLogAsynchronous specifies whether to enable the asynchronous output functionality for log files.
When using the asynchronous output functionality for log files, if you specify a value greater than 4096 in the -XX:HitachiOutOfMemoryStackTraceLineSize option or -XX:HitachiJavaClassLibTraceLineSize option, the functionality operates as if you specified 4,096 bytes for the number of characters per row of the stack trace that is output. When the specified number of bytes cannot be allocated, a warning message is output and no stack trace is output. In addition, if the number of characters in a row exceeds the specified number of characters, characters after "at" are deleted in order until the number of characters in that row is equal to the specified number. Then the character string of length equal the specified number of bytes is output.
