Build ID: M20090211-1700 Steps To Reproduce: 1. Create a new Java Project 2. Add commons-lang-2.3.jar to the build path 3. Create a new type with a method that has a non-void return type and follows the pattern get* (e.g. public String getName();) 4. Rename the method --> Internal Error java.lang.reflect.InvocationTargetException at org.eclipse.jdt.internal.ui.actions.WorkbenchRunnableAdapter.run(WorkbenchRunnableAdapter.java:96) at

information:
Is your project a 1.5 project ?
The project had workspace default compiler compliance settings which was 1.6.
We assume it has something to do with "org.apache.commons.lang.enum", as of Java >= 1.5 "enum" is a reserved word und thus the package name is invalid.
My guess is that the package name "org.apache.commons.lang.enum" is rejected as it contains a 1.6 keyword ("enum").
It works if I change the compiler compliance to 1.4, close the project and reopen it again.
