Shunsuke,
The LargeObject support in PL/Java is experimental and in the current 
version, the C-code will not be initialized (hence the error that you 
get). The code is there though, and if you want to play around with it, 
my guess is that the only thing you need to do in order to get it to 
work is to add the line:

    LargeObject_initialize(fcinfo);

somewhere near the end of function Type_initialize in the file 
pljava/type/Type.c, recompile and try again.

Regards,
Thomas Hallgren
