I am able to reproduce the NullPointerException with a standalone test.
I have created the following repository with the test case, https://github.com/stephraleigh/postgres-jdbc-npe-rep
Please let me know if you are able to clone and reproduce the NPE.
Thanks
Steph

>It will be hard to supply a reproducer since it seems to require lots of concurrent startups
Blind guess would be: a two-threaded test.
Thread 1: create & drop table in a loop
Thread 2: PgDatabaseMetaData.getTypeInfo & clear cache in a loop
>Your explanation seems plausible. I will add the suggested logging
That would be awesome.
