45 * This is a cut down version of TestJavacTaskScanner, which as originally written
46 * caused an IllegalArgumentException in AbstractDiagnosticFormatter as a result
47 * of calling task.parseType with a name whose resolution depended on the setting
48 * of the bootclasspath.
49 * This test has the same call, task.parseType("List<String>", clazz), but checks
50 * that the error is handled in a reasonable way by javac.
