Hi Sergey,

I think the bug is in the readObject routine. It sets the initial size of the arrays based on if the number of segments/coords is "< 0" and it sets them to INIT_SIZE or INIT_SIZE*2 accordingly. Those tests should be "< INIT_SIZE(*2)"...

Hello.
Please review the fix for jdk 9.
needRoom() method does not take into account that current array of types
can be empty. In this case it fails to increase it.
I handle this case and increase the size of the array by 1 instead of
INIT_SIZE, because I assume that the user intentionally try to decrease
memory usage.
