Has anyone ever seen this?
When I click 'step over', Eclipse doesn't pause at the next line. It
runs to the next breakpoint. Mouse and Fn key behave the same.
I can work around this by setting a breakpoint on every line. What
could I be doing wrong? Is there some configuration setting I'm missing?
This is a Java application on Linux, Eclipse 3.4.1.

Line Number Table is a mapping from Java source code lines to bytecode
offsets. If you set a breakpoint in a method without this information,
the debugger does not know where to suspend the execution of bytecode.
JDT usually warns, when a user sets a breakpoint in such a method. But
the warnings may be turned off.
To check the setting for your own project in your workspace, go to
Project > Properties > Java Compiler
The checkbox called 'Add line number attributes to generated class
files' should be on.
Anyway, you say, your problem disapeared...

Peter
