Bug 12101 NewTypeWizardPage.createType crashes in non-ui thread
When performing the IRunnableWithProgress from NewTypeWizardPage.getRunnable, I get the stack-trace shown below. This is caused by a creation of the JavaTextTools object. Currently, my workaround is to call JavaPlugin.getDefault().getJavaTextTools() in the constructor of the class that I derive from NewTypeWizardPage.
