java.lang.VerifyError: Constructor must call super() or this() before return

Question

I am getting the following error:

Exception in thread "AWT-EventQueue-0" java.lang.VerifyError: Constructor must call super() or this() before return in method freetts.FTall.()V at offset 0 at freetts.FormTTS.MenuContinueButtonActionPerformed(FormTTS.java:429) at freetts.FormTTS.access$100(FormTTS.java:59) at freetts.FormTTS$2.actionPerformed(FormTTS.java:127) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2018) at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2341) at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:402) at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:259) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(BasicButtonListener.java:252) at java.awt.Component.processMouseEvent(Component.java:6505) at javax.swing.JComponent.processMouseEvent(JComponent.java:3321) at java.awt.Component.processEvent(Component.java:6270) at java.awt.Container.processEvent(Container.java:2229) at java.awt.Component.dispatchEventImpl(Component.java:4861) at java.awt.Container.dispatchEventImpl(Container.java:2287) at java.awt.Component.dispatchEvent(Component.java:4687) at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4832) at java.awt.LightweightDispatcher.processMouseEvent(Container.java:4492) at java.awt.LightweightDispatcher.dispatchEvent(Container.java:4422) at java.awt.Container.dispatchEventImpl(Container.java:2273) at java.awt.Window.dispatchEventImpl(Window.java:2713) at java.awt.Component.dispatchEvent(Component.java:4687) at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:707) at java.awt.EventQueue.access$000(EventQueue.java:101) at java.awt.EventQueue$3.run(EventQueue.java:666) at java.awt.EventQueue$3.run(EventQueue.java:664) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:76) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:87) at java.awt.EventQueue$4.run(EventQueue.java:680) at java.awt.EventQueue$4.run(EventQueue.java:678) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:76) at java.awt.EventQueue.dispatchEvent(EventQueue.java:677) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:211) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:128) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:117) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:113) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:105) at java.awt.EventDispatchThread.run(EventDispatchThread.java:90)

I am checking my program after a month or so, earlier the same code didn't give errors, I suppose I have not changed anything that could be causing this. I tried to solve the problem; so in the error in the 1st line it is mentioned:

at freetts.FormTTS.MenuContinueButtonActionPerformed(FormTTS.java:429)

So I opened FormTTS.java:429 Here is that code:

private void MenuContinueButtonActionPerformed(java.awt.event.ActionEvent evt) {                                                   

        FTall allform = new FTall();
        FTdirect directform = new FTdirect();
        FTsmall1 small1form = new FTsmall1();
        FTsmall2 small2form = new FTsmall2();
        FTsmall3 small3form = new FTsmall3();
        FTbig1 big1form = new FTbig1();
        FTbig3 big3form = new FTbig3();
        FTmc1 mc1form = new FTmc1();
        FTmc2 mc2form = new FTmc2();
        String S = (String) jCB2.getSelectedItem();
        String R = (String) jCB3.getSelectedItem();
        String P = (String) jCB4.getSelectedItem();
    .....

Line 429 particularly is:

FTall allform = new FTall();

And this is the code of the constructor being called:

public FTall() {
    initComponents();
}

It sounds like your FTall constructor is broken. Please post that code. — Jon Skeet
Jon Skeet, Maciej Cygan: which FTall code?? i mean FTall is another file, (see in the image: FTall.java) — Daksh Shah
@JonSkeet This seems to be a bytecode error not representable as legal Java source code. — Marko Topolnik
@DakshShah: Don't show a picture of FTall - include the source code of the constructor. — Jon Skeet
