NullPointerException within HikariDataSource.shutdown() about hikaricp

[brettwooldridge]

When HikariDataSource is used without HikariConfig the pool is lazily constructed upon first call to getConnection() because there is no way to know when configuration of the datasource is complete. So this is a legitimate bug. The shutdown() method need to include a null check for pool.

The fix is committed to the dev branch and will appear in the 1.3.4 release later this week.

You can build the dev branch to verify the fix if you wish:

git clone https://github.com/brettwooldridge/HikariCP.git
cd HikariCP
git checkout dev
mvn install

Then use version 1.3.4-SNAPSHOT as a maven dependency or use the target/HikariCP-1.3.4-SNAPSHOT.jar directly.
