Mono uses a conservative GC, so may be they just don't notice that IRAF
is garbage. On .NET ikvm runs fine:
C:\>ikvm IRAF foo
java.lang.SecurityException: Operation not allowed
at java.lang.SecurityManager.checkPermission(Unknown Source)
at java.lang.SecurityManager.checkWrite(Unknown Source)
at java.io.RandomAccessFile.<init>(Unknown Source)
at java.io.RandomAccessFile.<init>(Unknown Source)
at IRAF.main(Unknown Source)
at IRAF.main(Unknown Source)
java.lang.NullPointerException
at java.io.RandomAccessFile.write(Unknown Source)
at IRAF.main(Unknown Source)
at IRAF.main(Unknown Source)Another interesting trick with the finalizer is creating instances of classes that have a private constructor! The attached runtime.j creates an instance of (a subclass of) java.lang.Runtime. Doesn't work on ikvm, because it ignores "new" without a corresponding call to the constructor. It could be considered a bug in Sun's verifier that it allows a class without a constructor, what do the other VMs do with this code?
