Description Steffen Pingel

The isEmpty() method does not exist in Java 1.5.

Fixed -- the toString part wasn't needed at all. Not sure why Eclipse didn't note this as the BREE is 1.5.

Comment 2 Steffen Pingel

I believe you need to have an actual Java 1.5 JRE registered to get error markers.

Comment 3 Miles Parker

Ah. And since there isn't one on the Mac... I wonder if API baselines would/could provide this?

OK, we really need a better way to catch these, it's not likely that I'm going to remember to avoid that. Ad there doesn't seem to be a good way around this form what I can find online. Why isn't the automated build catching these?

Comment 6 Steffen Pingel

2011-09-28 20:21:55 EDT

It's probably building with Java 1.6. A very simple way to catch these in the workspace is to configure a Java 1.5 runtime environment in Eclipse (comment 2).

Comment 7 Miles Parker

2011-09-28 21:09:28 EDT

Again, that doesn't work on Mac OS X, because there is no JRE 1.5 on the mac. (comment 3)

Please see bug 359324 for a partial solution.

Sounds like this can indeed be done using API tooling: http://dev.eclipse.org/mhonarc/lists/cross-project-issues-dev/msg06643.html. Do you know where to install execution environments from?

Yep, we're all set:
