Mohamad,
Sorry that you are seeing this issue. I could not replicate the issue at my end with MyEclipse 2015.
Can you please give us more information to help us investigate further?
1. Are you debugging a JSP or Class file?
2. Are you sure that the current line of execution is *after* the line that instantiates the value you are trying to evaluate?
3. Please switch to a new workspace, configure the Websphere server, replicate the issue with the debug and check if there are any error logged in the .log file located at workspace dir/.metadata/.log. If yes , then please send us the .log file for further investigation.
4. Also share with us the MyEclipse Installation Details from MyEclipse > Installation Summary > Installation Details along with the exact version of Websphere Application Server to help us replicate the issue at our end.
5. If possible, can you please try to reproduce the issue, using Tomcat, with any of the projects from the Examples on Demand repository (MyEclipse > Examples On-Demand or from MyEclipse Examples in the CVS Repositories view) to narrow down the issue?
Let us know how it works for you.
