[jboss-jira] [JBoss JIRA] Commented: (EJBTHREE-1994) ServiceContainer.dynamicInvoke can lead to NPE

[Andrew Lee Rubinger (JIRA)]

    [ https://jira.jboss.org/jira/browse/EJBTHREE-1994?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12507503#action_12507503 ] 

Andrew Lee Rubinger commented on EJBTHREE-1994:
-----------------------------------------------

I'd instead opt for one of our own "MethodNotPresentException extends RuntimeException"-type thing.  NoSuchMethodError is a LinkageError type:

"Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed."

> Looking at the other containers (like StatelessContainer) they too can lead to such a NPE. The containers need to throw NoSuchMethodError or something more meaningful in the absence of a method.
