Hi All,
We are intermittently getting mvel compilation errors with the following:
Caused by: java.lang.IllegalArgumentException: object is not an instance of
declaring class
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at
sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39
)
at
sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl
.java:25)
at java.lang.reflect.Method.invoke(Method.java:585)
at
org.mvel.optimizers.impl.refl.MethodAccessor.getValue(MethodAccessor.java:61
)
... 148 more
The rules compile ok and the application will run normally (rules processing
successfully) for a few days then this error will occur. Tried to replicate
but once the application is restarted the last action before the failure is
repeated and always processes successfully.
Any help would be appreciated.
Regards
JS
