In Java 9 the format of "java.version" has changed in JEP223 (http://openjdk.java.net/jeps/223) to no longer use the 1.x.* format, but instead use "9*" format.
With Java 9 early access (9-ea) release, expression with "@annotation" throws the following exception:

java.lang.IllegalArgumentException: error the @annotation pointcut expression is only supported at Java 5 compliance level or above
	at org.aspectj.weaver.tools.PointcutParser.parsePointcutExpression(PointcutParser.java:301)

On first sight the problem is that in:
"util/src/org/aspectj/util/LangUtil.java"

java.version string is parsed as:
try {
	String versionString = vm.substring(0, 3);
	Double temp = new Double(Double.parseDouble(versionString));
	vmVersion = temp.doubleValue();
} catch (Exception e) {
	vmVersion = 1.4;
}

vm is the "java.version" system variable, that no longer follows the 1.x format (in early release case it is 9-ea, on the stable release it will be simply "9", and with later minor/major releases 9.x.y).
9-e will not be parsed to Double and will throw an exception, so vmVersion is set to 1.4.
