Hi There,

I use Rhino1_5R41 and encountered exception as below:
-----------------------------------------------------------------------
java.lang.RuntimeException: java.lang.ClassFormatError:
org/mozilla/javascript/gen/c-2147483648 (Illegal Class name
"org/mozilla/javascript/gen/c-2147483648")
 at org.mozilla.javascript.optimizer.Codegen.compile(Codegen.java:113)
 at org.mozilla.javascript.Context.compile(Context.java:2018)
 at org.mozilla.javascript.Context.compile(Context.java:1948)
 at org.mozilla.javascript.Context.compileReader(Context.java:899)
 at Rhino.compile(Test.java:65)
 at Test.main(Test.java:27)
-----------------------------------------------------------------------
org.mozilla.javascript.optimizer.OptClassNameHelper#getJavaScriptClassName()
is used to name the Java class compiled from javaScript.
In the OptClassNameHelper#getJavaScriptClassName(), the globalSerial
value is used, except function, to name the class to guarantee
uniqueness of the class name.
The globalSerial value type is int, and static defined, so if you
continue to compile JavaScript and create JavaClass, you will reach the
value of Integer.MAX_VALUE(2147483647) eventually.
If you goes on, the globalSerial value turnes into Integer.MIN_VALUE
(-2147483648) and compile would failed because of Java class name must
not contain the '-' character.
I think this is bug.
Is it right?
And I suggest that globalSerial value would be reset to 1 before
over-flow.
Does this measure cause any problem?

Regards,
 Tomohiro
