Omar Al-Safi commented on CAMEL-15320:
--------------------------------------
[~loks007divi] the issue reported in CAMEL-15064 occurs if you use the groovy
script, If you'd use the java dsl, this shouldn't occur. However, would be nice
if you can attach the logs and with the route code that you use in order to
reproduce this issue from our end.
