Invalid stack height compiler error
Hello Byteman
I'm using a set of rules to examine thread pool usage in Wildfly. The same ruleset compiles and executes on Wildfly when running locally, but fails to pass a type check when running on a remote test server. Both are using JDK 8 to run the test program. I wonder if you could help me determine what the problem is.
Here is the ruleset: I set up a counter associated with a collection of threadpools to allow me to display threadpool state every X method calls for methods which make use of the threadpool.
