Doc Text:
The MSSQL JDBC connection invalidates Kerberos tickets because it calls the GSSCredentials.dispose() method during close(). The Kerberos ticket (TGT) is shared among connections which means that the first closed connection in EAP's connection pool invalidates TGT and every subsequent attempt to obtain a new connection fails. This is cause by the MSSQL JDBC driver' architecture. To wrk around this issue, set the datasource's "idle-timeout-minutes" property to a high value.

Description Juraj Duráni 2015-08-26 13:02:49 UTC 
The MSSQL JDBC connection calls GSSCredentials.dispose() during close(). The TGT 
is shared among connections. It means, that the first closed connection in EAP's connection pool invalidates TGT and every next try to get new connection fails. 
This is cause by architecture of the MSSQL JDBC driver.
