the information, that it's not possible reduce the filesystem size of a jfs filesystem while it's mounted should be enough for not using it

in jfs number of inodes are fixed,in jfs2 dynamically inodes are generated
jfs inode size will be max 128 bytes ,in jfs2 max size is 512 bytes
jfs have only one log file but jfs2 every FS can have own log file
log file is observe the process in file system

only reason for using jfs is need for compression. Else always choose JFS2
