I had this same problem last month when I moved to GWT 1.5.2 also. It turned out to be a conflict between GWT's dev library and the Jasper 2 JSP engine which apparently uses the Eclipse JDT Java compiler. The jasper-compiler-jdt.jar had conflicting versions of the org.eclipse.jdt.internal.compiler.Compiler class. Check your GWT project build path for that jar file and remove it.
Hope this helps... Tom Deep wrote: > I'm using Mac OS 10.5.5 & Eclipse 3.3.2 and I migrated my project from > GWT 1.4.61 to 1.5.2 and getting following error.
