Hi ,

I am working on creating an application using drools flow using version 5.0 of Drools.
I performed load test on the application using jmeter.
It works for fine for 10 threads simultaneously.
But when I increase the number of hits to 50,it gives me the following exception:

[Error: incomplete statement: (possible use of reserved keyword as identifier: )]
[Near : {... globals != empt ....}]
                      ^

I checked the files and I could not find any reserved keywords.
Please let me know how to resolve this issue.
