Porting JVM to MINIX

Hi,
As you may see from the title, for some reason I need to make running .class files on Minix possible (a compiler is not necessary). So could somebody point me in any direction, suggest some literature or give some advice? Generally, how would you do it?
Also how big is this project? I guess I should port openJDK and make some kind of interpreter. But I never did something similar. (I'm CS student on second year)

I have also read Tanenbaum's "operating systems design and implementation". It gave me a lot of insight of minix internals.


Thanks in advance

NAME
mkfs.minix - make a Minix filesystem SYNOPSIS
mkfs.minix [options] device [size-in-blocks] DESCRIPTION
mkfs.minix creates a Linux MINIX filesystem on a device (usually a disk partition). The device is usually of the following form: /dev/hda[1-8] (IDE disk 1) /dev/hdb[1-8] (IDE disk 2) /dev/sda[1-8] (SCSI disk 1) /dev/sdb[1-8] (SCSI disk 2) The device may be a block device or a image file of one, but this is not enforced. Expect not much fun on a character device :-). The size-in-blocks parameter is the desired size of the file system, in blocks. It is present only for backwards compatibility. If omit- ted the size will be determined automatically. Only block counts strictly greater than 10 and strictly less than 65536 are allowed. OPTIONS
-c, --check Check the device for bad blocks before creating the filesystem. If any are found, the count is printed. -n, --namelength length Specify the maximum length of filenames. Currently, the only allowable values are 14 and 30 for file system versions 1 and 2. Ver- sion 3 allows only value 60. The default is 30. -i, --inodes number Specify the number of inodes for the filesystem. -l, --badblocks filename Read the list of bad blocks from filename. The file has one bad-block number per line. The count of bad blocks read is printed. -1 Make a Minix version 1 filesystem. This is the default. -2, -v Make a Minix version 2 filesystem. -3 Make a Minix version 3 filesystem. -V, --version Display version information and exit. The long option cannot be combined with other options. -h, --help Display help text and exit. EXIT CODES
The exit code returned by mkfs.minix is one of the following: 0 No errors 8 Operational error 16 Usage or syntax error SEE ALSO
fsck(8), mkfs(8), reboot(8) AVAILABILITY
The mkfs.minix command is part of the util-linux package and is available from https://www.kernel.org/pub/linux/utils/util-linux/. util-linux June 2015 MKFS.MINIX(8)
