Subject: Java crash when invaild csd 

Unfortunately users (me) are making mistakes. When csound compiles a bad 
CSD though the java csound APIs, the result is sometimes a Java VM 
crash, not an error return code of the Compile API..

1) an UDO used with a wrong number of parameters
error:  insufficient required arguments, line 207:
kpitch hpkcSeq kfseq, 6.0, 6.02, 6.04, 6.06, 6.08, 6.03, 6.05, 6.07
        instr   100
1 syntax errors in orchestra.  compilation invalid
#
# An unexpected error has been detected by HotSpot Virtual Machine:
#
#  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x77c0554a, pid=484, 
tid=544
#
# Java VM: Java HotSpot(TM) Client VM (1.5.0_09-b03 mixed mode, sharing)
# Problematic frame:
# C  [MSVCRT.dll+0x2554a]
#
# An error report file with more information is saved as hs_err_pid484.log
#
# If you would like to submit a bug report, please visit:
#   http://java.sun.com/webapps/bugreport/crash.jsp
#
*
2) Specifying the use of a MIDI device that doesn't exist in your system 
is also crashing the VM : -M0 option set in the CSD, in the csOptions 
field, will crash the VM.

Thanks

I had the impression that a try --- catch exception handling would have
sorted this out.
