I'm using CloudSQL with Hibernate (v 4.1.7) and sometimes opening new
connection to CloudSQL takes very long time. More precisely the problem is
in initialization of Bytecode provider. Usually it takes around 5 seconds,
but sometimes - 40-50 seconds! This problem causes Deadline exception for
requests. Could someone help me with this problem? Ask me more if needed.
Here is a log:
