The pool statistics "Available" shows wrong value after fill pool in EAP 6
Issue
The pool statistics' "Available" shows wrong value (one less than "max-pool-size") after fill pool.
For example, min-pool-size=5, max-pool-size=10 and prefill=true are set to datasource configuration:
<pool>
<min-pool-size>5</min-pool-size>
<max-pool-size>10</max-pool-size>
<prefill>true</prefill>
</pool>
Then, when checking pool stats via CLI after JBoss start-up, the results shows the following:
[standalone@localhost:9999 /] /subsystem=datasources/data-source=ExampleDS/statistics=pool/:read-resource(recursive=false,proxies=false,include-runtime=true,include-defaults=true)
{
"outcome" => "success",
"result" => {
"ActiveCount" => "5",
"AvailableCount" => "9",
"AverageBlockingTime" => "0",
"AverageCreationTime" => "3",
"CreatedCount" => "5",
"DestroyedCount" => "0",
"MaxCreationTime" => "4",
"MaxUsedCount" => "1",
"MaxWaitTime" => "0",
"TimedOut" => "0",
"TotalBlockingTime" => "0",
"TotalCreationTime" => "17"
}
}
