I get this error message after compiling my software with a new
release of the IAIK JCE 2.5 release (with thr 2.5beta 1 everything
worked fine). I don't think it is a problem with the IAIK-Software,
because of the internal error
(Review ID: 58010)

I'm getting the problem when I use IAIK's X509Crl class.

iaik.x509.X509CRL crl=new iaik.x509.X509CRL;

The error I'm getting is

N/A

This bug is being closed because the new javac compiler does not exhibit
this behavior.  No work on the old javac compiler is planned.  The new
javac compiler is shipping with the 1.3 release of J2SE.  The old compiler
is provided in 1.3 for backwards compatibility; it will be withdrawn in a
future release of J2SE.


======================================================================

Workaround: use the new javac-ea compiler!

This problem also occurs when any "obfuscated" class files are
used as an input to javac or javap.  (JDK 1.2.2 RC2 on Linux)
The issue is that MethodSet does not understand that a method
is uniquely identified by its name, argument types, and return
type.  Two methods with the same name and argument types,
but different return types (and YES, this is VALID by the
ClassFile specification) cause it to choke, thinking that they
are the same method.  MethodSet needs to check the return
type of the methods as well to uniquely identify them.

Come on Sun, at least implement your own Virtual Machine
Specification correctly!

I am getting this exception trying to compile a jsp under 
Tomcat 3.2.1 and jdk 1.3...
HELP!

I am getting the same error with JDK 1.2.2 on Mac OS X Public 
Beta. And there is no JDK 1.3 available for Mac OS X. I am 
forced to use the JDK compiler since I am using Ant as my 
build engine. No workaround!
