I am using Netbeans. I did some things with bindings and now whenever I start my program, before it even initializes the form, it gives me an error
The exception in thread main is occuring before the form is even an initialized object yet. The form is not even an object yet. Every line in my main()
causes an exception. Random stuff. I don't understand it at all.
Here is the error.
Exception in thread "main" java.lang.ExceptionInInitializerError

OBD2nerForm
line 731
is bindingGroup.bind();
sometimes it errors out on pack();
the exception in main()
does not even seem relevant because it occurs as soon as the program is run and every time I comment out a line it jumps to the next
public void actionPerformed(ActionEvent evt) {
jFormattedTextField2ActionPerformed(evt);
}
});

Help, I do not understand. What information do you need from me?
Edit: It seems to all be code which I cannot touch. I should probably add that this started with Netbeans adding about 200 invalid imports import jCheckbox1
which I deleted.
I found that I had bound jFormattedCheckBox1.foreground
to jCheckBox1[${selected}]
.... this was the problem. Thank you for your help.
It seems that a color should not be able to be bound to a boolean
. I guess bindings are an advanced feature?
I found the problem by deleting all of the controls, then running, then undoing and then deleting one at a time. When I found the offending control, I examined the properties.
Retrofit
have recently updated to 2.7.1 version. After that Android 4.x
clients have crashed. See https://stackoverflow.com/a/60071876/2914140.
Downgrade Retrofit
to 2.6.4.
I got same error and it was due to older Lombok version. Check and update your Lombok version, Changes in Lombok
v1.18.4 - Many improvements for lombok's JDK10/11 support.
@Christian Ullenboom' explanation is correct.
I'm surmising that the OBD2nerForm
code you posted is a static initializer block and that it is all generated. Based on that and on the stack trace, it seems likely that generated code is tripping up because it has found some component of your form that doesn't have the type that it is expecting.
I'd do the following to try and diagnose this:
My suspicion is that the root cause is a combination of something a bit unusual (or incorrect) with your form design, and bugs in the NetBeans form generator that is not coping with your form. If you can figure it out, a workaround may reveal itself.
Wherever there is errors or exceptions in static blocks, this exception will be thrown. To get the cause of this exception simply use Throwable.getCause()
to know what is wrong.
Hope this helps...
class SomeClass{
//Code snippet here...
}
Code snippet 1: Absolutely OK - all checked exceptions handled
static void m1(){
try{
throw new Exception();
} catch(Exception e){
System.out.println(e);
}
}
static{
m1();
}
Code snippet 2: Won't compile - unreported checked exception
static void m1() throws Exception{
throw new Exception();
}
static{
m1();
}
Code snippet 3: OK (see code snippet 1)
static void m1() throws Exception{
throw new Exception();
}
static{
try{m1();}
catch(Exception e){
System.out.println(e);
//or whatever
}
}
Code snippet 4: Compilation error, initilalizer must be able to complete normally
static{
throw new RuntimeException();
}
Basically it boils down to this:
This makes sense as A CLASS SHOULD BE ABLE TO COMPLETE INITIALIZATION NORMALLY. If this happens to be a problem, this should be categorized as an Error (from which recovery is usually difficult or impossible) rather than an Exception (which is usually recoverable)...
Make sure the project does not have any errors. Delete the project from workspace(make the workspace a different directory from the git folder) and import again.
