This is my eclipse.ini file after I changed it. This is the eclipse.ini file before I changed it:

    -startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20120522-1813

--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Dhelp.lucene.tokenizer=standard
-Xms40m
-Xmx512m

Anyone have any suggestions? I tried changing: -Dosgi.requiredJavaVersion=1.6 -Xms512m to -Dosgi.requiredJavaVersion=1.7 -Xms1024m with no luck

Answer 1

One reason is that your -Xms parameter (initial heap size) defines a larger heap size than the -Xmx parameter (maximum heap size), you should fix it. If after fixing it the problem remains try to revert to the original eclipse.ini file and apply the parameters one by one to see which is the other 'wrong one'.

Answer 2

You seem to have changed a lot of things in one go.

As a general strategy, I would suggest reverting to the original settings, and then make the changes one at a time, starting with the most important one ... or the one that is most likely to work.
