| Contributed test case for BTree by Christof Dallermassl (cdaller@iicm.edu):
-= quote from original message posted on jdbm-general =-
I tried to insert a couple of elements into a BTree and then remove
them one by one. After a number or removals, there is always (if more
than 20 elements in btree) a java.io.StreamCorruptedException thrown.
The strange thing is, that on 50 elements, the exception is thrown
after removing 22, on 200 it is thrown after 36, on 1000 it is thrown
after 104, on 10000 it is thrown after 1003....
The full stackTrace is here:
