what happened 
I copied some scala sources from a Java project where they had been sharing a package with java sources to a new\
 scala project created by the wizard. Then I tried to open one up to look at it. Multiple errors were thrown as \
a result, and they are in the log file. It's kinda flaky getting it to repeat this, but it seems to happen a lot\
.
