Guava 18 won't compile with GWT 2.8Snapshot and Java 8

I am using in my module gwt.xml and put

guava-18.0.jar
guava-gwt-18.0.jar

Edit: The google group GWT-Contributors is discussed: https://groups.google.com/forum/#!topic/google-web-toolkit-contributors/zYUfanL8zwM

Here is the issue for this issue: http://code.google.com/p/google-web-toolkit/issues/detail?id=9036

Is there a workaround for this problem?

Edit: I tested with Guava 19SNAPSHOT and got the same error.

This is a known issue with GWT and the version of the JDT used.

The fix reported in the bug report is to update the jdt version, run update-jdt.py, and update dev / build.xml to point to the new version.



Alternatively, you can try different versions of guava, or start removing methods / classes from guava that don't work.

Or you can wait until a newer version of gwt is released that fixes these issues.
