[jboss-jira] [JBoss JIRA] Commented: (JASSIST-82) FieldAccess.getField() throws RuntimeException: javassist.bytecode.ClassInfo cannot be cast to javassist.bytecode.FieldrefInfo

--------------------------------------
I guess you called getFiled() after calling replace() on the same FieldAccess object.
Since replace() modifies the bytecode, getField() does not work any more. This is a
specification for performance.
FieldAccess.getField() throws RuntimeException:
javassist.bytecode.ClassInfo cannot be cast to javassist.bytecode.FieldrefInfo

Issue Type: Bug

My code calls javassist.expr.FieldAccess.getField() on an instrumented class. This method
call fails with a RuntimeException: javassist.bytecode.ClassInfo cannot be cast to
javassist.bytecode.FieldrefInfo:
java.lang.ClassCastException: javassist.bytecode.ClassInfo cannot be cast to
javassist.bytecode.FieldrefInfo
