I tried to solve the issue with parsing exception in init like this:
` @Override
public <T> T evaluate(Exchange exchange, Class<T> type) {
if (expressionException == null) {
return expression.evaluate(exchange, type);
} else {
throw expressionException;
}
}
@Override
public boolean matches(Exchange exchange) {
if (predicateException == null) {
return predicate.matches(exchange);
} else {
throw predicateException;
}
}
@Override
public void init(CamelContext context) {
simple = context.resolveLanguage("simple");
text = context.resolvePropertyPlaceholders(text);
try {
if (resultType != null) {
Object[] properties = new Object[2];
properties[0] = resultType;
expression = simple.createExpression(text, properties);
} else {
expression = simple.createExpression(text);
}
expression.init(context);
} catch (RuntimeCamelException e) {
expressionException = e;
}
try {
predicate = simple.createPredicate(text);
predicate.init(context);
} catch (RuntimeCamelException e) {
predicateException = e;
}
}`
But not all testcases pass anyway as it looks like init() is not called
before the first call to evaluate() or matches()
