Re: The new 2.1M1 release appears to have a few challenges

[Lex Spoon]

The new data-flow optimizer is choking on the code.  Some sort of
uncommon syntax in the code is breaking one of its assertions.


Let me poke around a little to see what's up. Filed as Issue 4957:

The new 2.1M1 release appears to have a few challenges

[Paul Stockley]

The first issue I got when I compiled my app was a bunch of errors
related to source missing from the bikeshed application. I fixed this
by removing the bikeshed jar from:

\eclipse\plugins\com.google.gwt.eclipse.sdkbundle.
2.1.0_2.1.0.m1-201005191217

After doing this development mode seems to work OK. However when I
compile my application I get

 [ERROR] An internal compiler exception occurred
com.google.gwt.dev.jjs.InternalCompilerException: Unexpected error
