Denis Magda commented on IGNITE-1526:
-------------------------------------
Reviewed the latest pull-request
(https://github.com/apache/ignite/pull/151/files).
Have the following comments.
1) I don't like that we explicitly define {{serialVersionUID}} in several
examples ({{private static final long serialVersionUID = 0L}}. The examples are
not intended to be demonstrated or run in the heterogeneous environment and
such explicit definition of {{serialVersionUID}} will confuse the end user
because it looks like he/she must always define this variable on its own.
My suggestion is to exclude these examples from the test cycles and revert the
changes done in their code. We can safely do this because these examples don't
reveal new bugs for the heterogeneous scenario.
2) Why {{USE_DFLT_SUID}} is initialized to {{false}} by default? What is about
compatibility?

> There are several issue related to IBM JDK.
