I've created a Java application which uses a .properties file.
Initially I had the below property:
manager.url=https://1.2.3.4/manager-bucket1
As the application and my properties file grew I found that I was duplicating many things in my .properties file so for ease of maintenance I did the following:
manager.ip=1.2.3.4
manager.bucket=manager-bucket1
manager.url=https://${manager.ip}/${manager.bucket}
When I execute my application using the new properties I get an IllegalArgumentException:
Illegal character in path at index 30: https://1.2.3.4/manager-bucket1
java.lang.IllegalArgumentException: Illegal character in path at index 30: https://1.2.3.4/manager-bucket1

I can't see anything obvious that might be causing this. Could it be something to do with the text encoding and if so how can I resolve the issue?
As VGR pointed oout, there was a hidden space character at the end of one of my lines. I identified it by pasting the file contents into Word and clicking the "Show all non-printing characers" button. Once it was removed my application ran without error.
