orig synopsis: "Out of memory in JavaC/JIT compilers, with no stack trace"

8 May 2001, eval1127@eng -- doubt we can put the fix into 1.3.1
at this point, since it was fixed only in merlin (1.4) code base.

Problem is reproducible with build 24 of 1.3.1:
java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-b24)
Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed mode)

-------------------
java version "1.3.1-rc2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-rc2-b23)
Java HotSpot(TM) Client VM (build 1.3.1-rc2-b23, mixed mode)

This Problem report is a duplicate of 4428664 and 4368309
which I believe have been closed prematurely.

 Please note that it would be really nice to be fixed before
final release of 1.3[.1]. Sun is currently at release candidate 2, with
(I hope) the intent of taking the 1.3[.1] architecture to final release.
This bug is stated to be fixed in 1.4 (Merlin) But I believe that
there must be a number of companies out there that would like to
release production code using the 1.3[.1] final release. (Mainly because
it is faster) As this problem also effects the rum-time compiler
it is difficult to prove that there are no large switch numbers
in the library code. (i.e. Swing) Is it possible to get the Merlin
fix back-tracked into the 1.3[.1] JavaC and JIT compilers?

I am currently in a position where I will have to write a Lint
like program to search the library (Swing et. al.) class files
for large switch numbers. Any help would be appreciated.

Test case from earlier bug # 4411025:

public class SwitchTest {
     public static final int MEMENTO_NULL = 0x7FFFFFFD;
     public static final int MEMENTO_ALLE = 0x7FFFFFFE;
     public static final int MEMENTO_LEER = 0x7FFFFFFF;

     public static void main(String[] argv) {
         int i = MEMENTO_LEER;
         switch (i) {
         case MEMENTO_NULL:
             System.out.println("Null");
             break;

         case MEMENTO_ALLE:
             System.out.println("Alle");
             break;

         case MEMENTO_LEER:
             System.out.println("Leer");
             break;
         }
     }
 }
