[Squirrel-sql-users] Issue launching squirrel client

[Greg B. <gjb...@ho...>]

I have been using squirrel for many years. Normally, I can figure out any issues on my own but it seems I have a corrupt file somewhere and the stack trace is not helping. I am getting the below error when I attempt to launch the application. I have downloaded a fresh copy the latest stable build 4.5.1 and installed it in different locations (both the zip and the installer). I have tried Amazon Corretto [C:\Program Files\Amazon Corretto\jdk11.0.19_7\bin] and Eclipse Adoptium [C:\Program Files\Eclipse Adoptium\jdk-11.0.19.7-hotspot\bin] but EVERY instance has the same error. The splash screen starts gets about ¾ through then gives me this error. If I had any idea what file it is trying to read and failing at I would fix it. Please help.

Hi.


If the error is common across 3 applications, then I guess it is not a 
Squirrel problem.


Maybe try re-installing Java?


What changed between the time it worked, and when it stopped working?

Re: [Squirrel-sql-users] Issue launching squirrel client

[Greg B. <gjb...@ho...>]

The location I was running the application from was a microSD card that seems to have a few issues. After I discovered this, I tried moving the folder to my primary drive and relaunching and that is when this started. I believe it is trying to read a configuration file from my user profile location and that the file may e corrupt but I do not know what file or where it may be looking. One of those AppData folder issues, maybe?

Seems like you're having a corrupt "RecentFilesJsonBean.json":

* 
https://github.com/squirrel-sql-client/squirrel-sql-code/blob/1a950b28b/sql12/core/src/net/sourceforge/squirrel_sql/client/Application.java#L1060
* 
https://github.com/squirrel-sql-client/squirrel-sql-code/blob/1a950b28b/sql12/core/src/net/sourceforge/squirrel_sql/client/util/ApplicationFiles.java#L200-L202

Try deleting it (move it away or rename it):

 > ren %USERPROFILE%\.squirrel-sql\RecentFilesJsonBean.json 
RecentFilesJsonBean.json.bak

Alternatively, you may open it in Notepad – if the content is empty (as 
it seems from the exception message), enter an empty JSON object and 
save it back:

{}

Stanimir,

THANK YOU SO MUCH!
You were 100% on target with that (two of the .json files were 100% empty/blank). I figured it was a corrupt file I just did not know where to look. Back up and running. You ROCK!!!! Thank you again!

Sorry for the inconvenience.

I just committed a change that should prevent such problems in the 
future. The according change log excerpt is:

Prevented SQuirreL from failing to start when an erroneous Json 
configuration exists. Such an error will now be logged and a 
default/empty configuration will be used.
