Hello,
Another finding from bringing up our webMethods 9.7. Upon adding CA Wily Introscope 9.7 JVM arguments to our custom_wrapper.conf for our default IS instance, we noticed the the JVM would exit upon launch. This was because of an issue with JVM 1.7 and profilers that use byte-code instrumentation for 1.5 which Wily 9.5.1.0 does. To remedy this we had to add the following to our custom_wrapper.conf wrapper.java.additional.204=-XX:-UseSplitVerifier. You can read more about -XX:-UseSplitVerifier at Oracle. A quick summary is it may lengthen the IS bootup time. Perhaps a Wily upgrade would remedy this issue, but we are not going to be upgrading Wily to resolve this single issue.
Good luck with 9.7.
Zach
