The following code is a simplified version of a machine-generated java code,
it is compiled successfully with JDT's internal Java compiler, but when
runs, it produces error message:
------
java.lang.VerifyError: (class: Bug, method: bug signature: (I)I) Illegal
default target in switch
Exception in thread "main"
------
However, I can compile and run it without any problem using Sun's JDK 1.4, I
think it is an internal bug, anyone who can help ?
----------------------bug code---------------
public class Bug
{
public static void main(String[] args)
{
int i = bug(123);
System.out.println(i);
}
public static int bug(int ppp)
{
switch(ppp) {
case 1:
case 2:
if (true) return(3);
break;
case 4:
break;
default :
break;
}
return(-1);
}
}
-------------------------------------

Sorry for the incomplete error message, the correct error message is :
----
java.lang.VerifyError: (class: jasn/parser/AsnParser, method: integerValue
signature: (Ljasn/parser/IntegerTypeInfo;)Ljasn/parser/BaseValueInfo;)
Illegal target of jump or branch
Exception in thread "main" make: Error code 1

It sounds like https://bugs.eclipse.org/bugs/show_bug.cgi?id=37621 which is
fixed in the latest 3.0 integration build and that will be in a next 2.1.1
maintenance build.
If you find that this is a different problem, do not hesitate to enter a bug
against JDT/Core.
