Update causes Eclipse to fail to be able to set breakpoints

[Carl Fletcher]

The latest security update for openjdk (on 2012-09-11) now causes Eclipse to fail to be able to set a breakpoint in code.

Steps to reproduce:
1. Install Eclipse Juno
2. Create a Java project, with a class
3. Attempt to set a breakpoint on a line of code

What happens is you get a popup with the message "The chosen operation is not enabled". There is also an option in the context menu to "Toggle Breakpoint Enablement". This gives the same error popup. It did not appear to deposit anything in the Eclipse .log

The only way I've found to fix this is to install the Sun/Oracle JDK and use that instead, breakpoints work OK then.

Clearly this could be a bug in Eclipse, but it didn't happen at all, and then it started happening with the latest openjdk update, so I'm filing it here and will move it if I get guidance to do so.

My environment:
I am not using Eclipse from Ubuntu repositories, I am using the main download from eclipse.org (Build id: 20120614-1722)

Ubuntu 12.04.1 LTS

Same problem using Eclipse Juno on Kubuntu 12.4. No error reported in Eclipse error log

Any news of a workarround or something??¿¿

Hi José

No news but I tried a simple workaround.

Install Sun Java JDK 1.7.0_7 (if you are using Ubuntu or Linux distro
with alternatives set it as default java with update-altervatives )
That fis the problem

Workaround is to use the Oracle JDK, or install the previous version and pin it.

Confirmed this is now fixed. Thanks!
