ADDITIONAL SYSTEM INFORMATION :
Microsoft Windows [Version 10.0.19045.3570]

A DESCRIPTION OF THE PROBLEM :
Run the testcase. This issue is not reproducible in openjdk 22-ea+19-1460. If this was fixed in version 22, the fix probably needs to be backported to version 21.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Compile the testcase using "javac -g --release 21 --enable-preview Test.java"
2. Run "java --enable-preview Test"

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Exception in thread "main" java.lang.IllegalArgumentException: Not a number
        at Test.main(Test.java:10)
ACTUAL -
Error: LinkageError occurred while loading main class Test
        java.lang.ClassFormatError: Illegal field name "" in class Test

---------- BEGIN SOURCE ----------
public class Test
{
    public static void main(String[] args) {
        try
        {
            System.out.println(Double.valueOf("not a number"));
        }
        catch (NumberFormatException _)
        {
            throw new IllegalArgumentException("Not a number");
        }
    }
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Compile classes without debug symbols (remove "-g")

FREQUENCY : always
