I've got an STS problem that's got me beat. Really hope someone can help. I'm writing an application that is deployed to Tomcat 7.0.12. The application can be published to the server and the server started without any problems.
Recently, when setting a breakpoint then starting the server in debug mode, I get the message:
Unable to install breakpoint in ... due to missing line number attributes. Reason: Absent Line number information.
Debugging on the server used to work for me! I don't know what I changed to break this. Maybe the upgrade to 2.7.0?? My Java compiler settings are set to add line number attributes. There is no explicit build.xml file, the Tomcat server settings are the default ones. Breakpoints are set in my application code only.
If no breakpoints are set, the server starts in debug mode without complaint, but ignores any breakpoints that are set while the server is running.
Does anyone have any idea what's going on?
