When I use hsqldb I have problems with GUI (JavaFx)

Question

I can't understand how RDB can be linked with GUI but I've checked several times. I have osgi javafx application. when I install hsqldb and use database I have strange problems: Before that I used h2 and I didn't have anything like that. And the only thing was changed is the RDB. I've checked on centos 7.1 and win 7 (VBOX) result is the same.

1) When I press CTRL+SHIFT I get a lot of the following exceptions:

java.lang.ArrayIndexOutOfBoundsException: 85
    at sun.awt.X11.XEvent.getFieldsAsString(XEvent.java:86)
    at sun.awt.X11.XWrapperBase.toString(XWrapperBase.java:37)

2) My javafx data binding stop working
3) When I close application via CTRL+C I get the following:

HOW TO FIX IT?

Answer 1

I've got the answer from Fred Toussi (Fred, thank you):
The hsqldb.jar contains the DatabaseManagerSwing which is a GUI app. You can compile HSQLDB with the Gradle or Ant (see the /build directory) as hsqldbmain.jar which excludes the Swing classes.

There was an old bug that showed some JDK had a problem with the Swing classes. https://sourceforge.net/p/hsqldb/bugs/1304/
