JAVA error : java.lang.NegativeArraySizeException

Question

Hello Experts,
We have a JAVA application which runs the below query. The application is scheduled to run as a job once every month. We notice that when the application runs for the 1st time, then we get the below error :
**************Failed to execute SQL: select tablespace_name, total_mb, used_mb, pct_used, free_mb, recycle_mb, extendible_mb from all_mspace where tablespace_name in ('ORAUSER') order by tablespace_name

We have a JAVA application which runs the below query. The application is scheduled to run as a job once every month. We notice that when the application runs for the 1st time, then we get the below error :
**************Failed to execute SQL: select tablespace_name, total_mb, used_mb, pct_used, free_mb, recycle_mb, extendible_mb from all_mspace where tablespace_name in ('ORAUSER') order by tablespace_name

Sorry - but if you won't post the info needed to help you then you won't get any help.
You haven't posted ANY info about the Java version, JDBC jar version, databse name and version, Nor have you posted ANY of the Java code involved in creating the connection or executing the JDBC code.
And the query you did post is either wrong or uses a custom table/view named 'all_mspace'.
All of the above means we can't try to reproduce the problem or even SEE the line of code that might be causing the problem.
It also means we can't even guess what else your application might be doing BEFORE the problem part of the code executes or  WHERE the problem might be. I have no reason to think the problem is in the driver or, as the other responder's link mentions, that you are even using a connection pool.
No one expects people to post confidential info. You need to create the SMALLEST section of code that reproduces the problem and then post that. You need to do that just for your own troubleshooting purposes: remove ALL unnecessary code, and keep removing stuff, until the problem goes away or you get down to a small section of code. Then you can begin troubleshooting.
Good luck with your problem.
