CassandraCqlClusterFactoryBean doesn't consider maxConnections while validating coreConnection values [DATACASS-176]

[spring-projects-issues]

Sumit opened DATACASS-176 and commented

The max values should be set before setting core values.
Otherwise the core values will be compared with the default max values which is 8.

The stacktrace as below

Caused by: java.lang.IllegalArgumentException: Core connections for LOCAL hosts must be less than max (100 > 8)

Also when modifying min & max simultaneous connections

Caused by: java.lang.IllegalArgumentException: Min simultaneous requests per connection for LOCAL hosts must be less than max (110 > 100)
