This appears to be a duplicate of [NETBEANS-5757] and [NETBEANS-5832]. It
appears to be fixed in NetBeans 12.5.

Andrew James commented on NETBEANS-6062:
Regarding the JAR vs. IDE execution: (1) Yes, both executions used the same
version of Java (Java 15.0.2 Adopt Open JDK). And they gave different results.
I dug deeper by comparing the *{{javap -c}}* output for the following two class
files:
a) The Test.class file in the build\classes directory.
b) The Test.class file extracted from the assembled JAR file (the one
auto-created by NetBeans).
I changed the code to assign a different value to i (just to double-check
execution behavior):
{code:java}
i = 123; {code}
I also performed a full clean and build.
The execution results were unchanged: I got an output of {{*0*}} from the IDE
but I got *{{123}}* from the JAR.
The *{{javap -c}}* results showed that *the compiled contents from the
build\classes directory are different from the compiled contents from the JAR
file*.
Results from build\classes:
{code:java}
>javap -c build\classes\foo4\Test.class
Compiled from "Test.java"
class foo4.Test {
static int i; foo4.Test();
Code:
0: aload_0
1: invokespecial #1 // Method
java/lang/Object."":()V
4: return
}{code}
Results from the unzipped JAR file:
{code:java}
>javap -c unjar\foo4\Test.class
Compiled from "Test.java"
class foo4.Test {
static int i; foo4.Test();
Code:
0: aload_0
1: invokespecial #1 // Method
java/lang/Object."":()V
4: return static {};
Code:
0: bipush123
2: putstatic #7 // Field i:I
5: return
}{code}
As we can see, the version from the JAR file contains the code for the static
block. This is missing from the build\classes version.
This was surprising.
(I have not installed NetBeans 12.5 yet - I will update when I have had a
chance to do so).

[~andrewjames] I modified your ticket and added code tags.
I tried to reproduce your problem with NetBeans 12.5 on OpenJDK 16. Any chance
you tried NetBeans 12.5 to check if this is still a problem.
Are you sure when you execute the jar manually you're using the same JDK while
executing it inside NetBeans?
