   java OOM is occured again and dump is taken.
   throught eclipse memory analyzer, the leak roport "One instance of 
"org.h2.mvstore.MVMap" loaded by "sun.misc.Launcher$AppClassLoader @ 
0xe00cd650" occupies 219,162,096 (47.12%) bytes. The memory is accumulated in 
one instance of "org.h2.mvstore.MVMap" loaded by 
"sun.misc.Launcher$AppClassLoader @ 0xe00cd650".
   it seems like a bug in H2 storage,so I change backend storage from H2 to 
mysql.
