 * This is a cut down version of TestJavacTaskScanner, which as originally written

 * of calling task.parseType with a name whose resolution depended on the setting
 * of the bootclasspath.
 * This test has the same call, task.parseType("List<String>", clazz), but checks
 * that the error is handled in a reasonable way by javac.
