Problem in Driver class when performing the lookup for JDBC ini file in Windows environments

[maxrabbi]

Driver version

2.1.0.10

Redshift version

PostgreSQL 8.0.2 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.4.2 20041017 (Red Hat 3.4.2-6.fc3), Redshift 1.0.44903

Client Operating System

Windows 10

JAVA/JVM version

Temurin-11.0.17+8

Table schema

N/A

Problem description

The problem is caused by the line 920 of the Driver class (https://github.com/aws/amazon-redshift-jdbc-driver/blob/v2.1.0.10/src/main/java/com/amazon/redshift/Driver.java).
When the Driver class is loaded from a path location Windows like (i.e C:<my_folder>\redshift-jdbc42-2.1.0.10.jar), line 917, the next 920 fails to properly perform the substring operation since there is not / character.
This leads to a java.lang.StringIndexOutOfBoundsException exception.

Hi @maxrabbi, thanks for reaching out to us about this issue. it sounds like we need to look into modifying this line 920 to use an approach compatible with both windows and *nix platforms. mentioned line

You're more than welcome to open a PR with the fix for this since you've identified the issue, otherwise a member of our driver team can work to implement the fix. Just let us know your preference :) cc: @bhvkshah

Hi sorry for the late reply. I think it's probably better you work on that. I'm not sure I will be able to look at the PR process and submit it earlier than next mid-week.

Massimo.
