Hmm. A mono bug (or missing feature rather). If you compile the program below
with mcs it will generate an invalid custom attribute (according to the MS
runtime anyway) and if you compile it with csc and run it with mono you get the
error that you ran into.

using System;

public class Attr : Attribute
{
public Attr(object o) {}
}

[Attr(new object[] { 42 })]
class Program
{
public static void Main(string[] args)
{
typeof(Program).GetCustomAttributes(false);
}
}

Please file a mono bug.

Regards,
Jeroen

IKVM .32 versus Sun JVM 1.4.2 performance comparison

Hi- Is there a datasheet in the archives that compares the performance between IKVM .32 and Sun JVM 1.4.2? I'm not particularly set on IKVM .32 for comparison, but would like to compare with a version of IKVM and Sun JVM that has similar performance to .32 and 1.4.2, respectively. Here are a few areas of interest: * How do native implementations compare, say, in the String class? * How does BigDecimal perform? * How does Xerces compare when converted using IKVMC (parsing, serialization)? * How does HashMap and Hashtable perform, especially when hashcodes may not be optimal? Are there general known bottlenecks that make IKVM slower then Sun JVM that a client of IKVM should watch out for? The machine I'm checking performance on is fairly powerful: P4 dual core (2.40 GHZ and 1.50 GHZ) with 2GB RAM There is about 1000 ms difference in various workflows of my application between running under Sun JVM 1.4.2 and IKVM .32. At this time, I haven't found anything obvious under the nprof profiler.
