Sometimes, the Java editor (in Java or Debug perspective) doesn't set a breakpoint on double click or context menu click of the ruler. Reopening the specific file sometimes fixes it. Does not affect all open files.

Reproducible: Sometimes

Steps to Reproduce:
1. Open a Java file (possibly larger one)
2. Double click on a line to set a breakpoint

Is it that it doesn't set a line breakpoint but is instead setting a class breakpoint? Or does it not set any breakpoints?

No breakpoint at all. Not even after restarting. Works after -clean but not for long.

Can you attach an example Java file and provide more detailed information about where in the code you are trying to set the breakpoint?

I'll try, but (as usual) the files are part of a larger project with lots of dependencies (and lot more files: reactive4java.googlecode.com).

I am able to set a breakpoint at TestD.java:54 but sometimes it fails to set a breakpoint in Reactive.java:3292 for example. In this case, I can't set any breakpoint in Reactive.java at all.

It seems the breakpoint setting fails if I set a breakpoint, debug the application and while running or after it, I can't set breakpoints anymore unless I reopen the file and/or restart Eclipse).

No issues in the 4.x versions.
