Hi,
I’m trying to run my simulation recording with Gatling Recorder but the generated .scala cannot compile.
[INFO] Caused by: java.lang.IllegalArgumentException
[INFO] at scala.tools.asm.ByteVector.putUTF8(ByteVector.java:213)
[INFO] at scala.tools.asm.ClassWriter.newUTF8(ClassWriter.java:1092)

[INFO] at scala.tools.asm.ClassWriter.newConstItem(ClassWriter.java:1042)
[INFO] at scala.tools.asm.MethodWriter.visitLdcInsn(MethodWriter.java:1134)
Can you help me ?
Thanks
I’m using gatling 2.2.0 M2 integrated in Eclipse and I record our webapp under Tomcat.
Can you post the full stacktrace and where in your code this is occurring?
This is occured when Eclipse compiled the .scala or during the maven install but I don’t have information about the location in my code.

Thank you
Can you check if your simulation compiles with Gatling’s bundle ?
No, the simulation is not detected by Gatling Bundle 2.1.4 and I don’t have any compilation error.
Thanks
What encoding did you use when generating the simulation ?
Also, can you share your simulation please ?
Is it possible that there is too many lines in the files (3000 for 30 seconde of duration) ?
Classes with too many lines can cause problems but they do not end up with that kind of error.
It looks like there is some characters that could not be written because of an encoding issue, but it’s hard to tell what exactly is the issue without the source of your recorded simulation.
Simulation contains client data so I can’t share this file unfortunately 
Does formParam have a limit caracter length ? The error provide from an very long param in formParam
As per Java/Scala, there’s a 65k limit to String literals length, yes.
If that’s your issue, try using String concatenation, or a StringBuilder.
HI team,
I have the same problem.
In fact the record contains string with 123000 characters.
How can i make a record with automatic split string with more than limits 65556.
Split the string may be a unit solution but not sure good for the future.
