Steps to reproduce:

      1. Install an RPC plugin http://confluence.atlassian.com/display/CONFDEV/RPC+Module
      2. Use the service (remote client)
      3. Redeploy/upgrade the RPC plugin
      4. Upon next usage, Confluence returns IllegalArgumentException:
      AxisFault
       faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.generalException
       faultSubcode: 
       faultString: Tried to invoke method public abstract java.lang.String atlassian.confluence.extra.helloworldrpc.HelloWorldPublic.helloWorld() with arguments .  The arguments do not match the signature.; nested exception is:

      Flushing Confluence caches is not sufficient. A Confluence restart is required to get rid of the problem.

            Atlassian Update - 27 March 2025

            Hi,

            At Atlassian, our goal is to ensure we’re providing the best experience for our customers. With our new Data Center strategy, Atlassian's focus is on security, compliance, and performance and is a key driver in prioritizing bugs. Closing the bugs that do not fall into those categories will allow us to focus on the ones in the most current versions of our products.

            This bug is being closed due to a lack of engagement in the last four years, including no new watchers, votes, or comments; this inactivity suggests a low impact.

            Please note the comments on this thread are not being monitored.

            You can read more about our bug fix policy here and how we prioritize bugs.
