Hi Jiangli,

Thanks for noticing this. I have added the following to my patch for 
metaspaceShared.cpp:

-      tty->print_cr("%s%d space: " SIZE_FORMAT_W(9) " [ %4.1f%% of 
total] out of " SIZE_FORMAT_W(9) " bytes [100%% used] at " INTPTR_FORMAT,
+      tty->print_cr("%s%d space: " SIZE_FORMAT_W(9) " [ %4.1f%% of 
total] out of " SIZE_FORMAT_W(9) " bytes [100.0%% used] at " INTPTR_FORMAT,


mc  space:     21736 [  0.1% of total] out of     24576 bytes [ 88.4% 
used] at 0x0000000800000000
rw  space:   4229896 [ 23.4% of total] out of   4231168 bytes [100.0% 
used] at 0x0000000800006000
ro  space:   7227952 [ 40.0% of total] out of   7229440 bytes [100.0% 
used] at 0x000000080040f000
md  space:      6064 [  0.0% of total] out of      8192 bytes [ 74.0% 
used] at 0x0000000800af4000
od  space:   6404560 [ 35.4% of total] out of   6406144 bytes [100.0% 
used] at 0x0000000800af6000
st0 space:    102400 [  0.6% of total] out of    102400 bytes [100.0% 
used] at 0x00000007bfc00000
oa0 space:     65536 [  0.4% of total] out of     65536 bytes [100.0% 
used] at 0x00000007bf800000
total    :  18058144 [100.0% of total] out of  18067456 bytes [ 99.9% used]


Thanks
