Bug reference: 14165

PostgreSQL version: 9.4.0
Operating system: Windows+Linux
Description:

Dear Wizards,

I found a strange behaviour [3] using [1] in combination with a Linux Java
version "1.7.0_80" and also a Java 1.7 Windows version. The connection to
the database cannot be established. It works normally with Java 1.8. I have
both libraries in the library path [1][2] and removing [1] (and so using
library [2]) fixes the problem.

[1] postgresql-9.4.1208.jar
[2] postgresql-9.4-1201.jdbc41.jar
[3] "Something unusual has occurred to cause the driver to fail. Please
report this exception"
org.postgresql.util.PSQLException: Something unusual has occurred to cause
the driver to fail. Please report this exception.
org.postgresql.Driver$ConnectThread.getResult(Driver.java:361)
org.postgresql.Driver.connect(Driver.java:281)
java.sql.DriverManager.getConnection(DriverManager.java:571)
java.sql.DriverManager.getConnection(DriverManager.java:187)

Greetings, a fan,
