Description
Attempting to compile the Vaadin Framework project on JDK9 or JDK10 I run into following error:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.5.1:compile (default-compile) on project vaadin-server: Compilation failure
[ERROR] server/src/main/java/com/vaadin/util/ReflectTools.java:[90,18] cannot access com.sun.beans.introspect.PropertyInfo
[ERROR] class file for com.sun.beans.introspect.PropertyInfo not found
The use of com.sun.beans.introspect should be replaced with something compatible with JDK 8, 9 and 10.

Research direction
Start in server/src/main/java/com/vaadin/util/ReflectTools.java around line 90 and reproduce the Maven compilation failure on JDK 9 or 10. Identify the use of com.sun.beans.introspect.PropertyInfo and replace it with an approach compatible with JDK 8, 9, and 10; done means the vaadin-server project compiles without the inaccessible-class error.
