This fix is prepared by Tom R.

"The JDK14 version of StackTraceElement::decode is based on the JDK8 code which contains mixed usages of 
method->constants() and method->method_holder()->constants() assuming they point to the same thing. In the case of 
anonymous methods this isn't true. Usually this isn't a problem but if CDS is enabled the the version flag of 
method->method_holder()->constants() is non-zero but version of of method->constants() is 0 which causes the code to 
switch constants pools and it reads garbage. JDK-8140685 [1] refactored this code to remove this logic and the JVMCI 
version of this code should be converted to use the same scheme."

I tested tier1-2 and tier3-4-graal. All clean.

Thanks,
Vladimir
