Re: [staf-users] About STAF Exception

[Sharon L. <lu...@us...>]

The barrier you are hitting is the method length limit in JVM bytecode. It 
is 65535 bytes max (and your code is 66159 bytes).  Long methods, really 
long python lists or dictionaries defined in the source code, or anything 
like that will run up against this limit.  To get around it, you should 
try splitting up your code into smaller scripts.

Note that you can google for this error and find more information about 
it.  This error is not specific to STAF/STAX.  It's a Java error message.

[staf-users] About STAF Exception







Greetings,
 

I have selected more than 1000 testcases for testing purpose and put entry 
into STAX Job under which entire testing process is written. When I have 
tried to run the STAX Job with the help of STAXMon.jar then I got the 
exception at the compilation time. The occurred exception is given under 
the <Snip>...</End> section.

These type of exception doesn't occur in case of selecting less than 
nearly 1000 test cases for testing purpose.

Please provide the solution for this.

1000 test cases is not exact. It varies between 900 to 1100.

Please let me know why this exception is occurred? What are the possible 
solutions to avoid this situation and running more than 1000 test cases at 
a time.
 
Can we execute 10000 test cases at a time?
 
With best regards,
Mohammad Shahid Jamal
