Denis Magda commented on IGNITE-2108:
-------------------------------------
The issue disappears if to replace H2DemoStoreFactory implementation with the
following
{noformat}
private static class H2DemoStoreFactory<K, V> extends
CacheJdbcPojoStoreFactory<K, V> {
@Override public CacheJdbcPojoStore<K, V> create() {
setDialect(new H2Dialect());
setDataSource(JdbcConnectionPool.create("jdbc:h2:tcp://localhost/~/schema-import/demo",
"sa", ""));
return super.create();
}
}
{noformat}
It means that a default constructor, that is used in the current
implementation, is not got called during deserialization. The issue is
reproduced on both optimized and binary marshallers.

> When a cache is started dynamically and has an implementation of

> {noformat}
> The reason is that in version 1.5 {{CacheJdbcPojoStoreFactory}} was reworked
> significantly and presently it has field {{private transient DataSource
> dataSrc}} that must be initiated somehow after deserialization.
> The issue is easily to reproduce with schema-import example:
> 1) complete all the steps described in the demo tutorial
> https://apacheignite.readme.io/docs/automatic-persistence#example
> 2) Start a remote node using {{DemoNode}}
> 3) Start {{Demo}}
> 4) The node started with {{DemoNode}} won't be able to start a cache because
> of the issue with the storage described above
