Subject: [daemon] fails start with Java debugging enabled

Hello,

I have a problem with Commons Daemon 1.0.4 and JDK 6u21 / 6u23 (both
32-bit and 64-bit). I have observed it both on Microsoft Windows 7 and
Windows Server 2008 R2. It did not exist with Commons Daemon 1.0.2 on
Windows Server 2008 R2.

I cannot use Java Debug Wire Protocol (JDWP) for the purpose of remote
service debugging.

As soon as I am starting newly installed service it stops executing.

The relevant service log part looks as follows:

[2010-12-21 10:08:41] [debug] ( prunsrv.c:1396) JVM destroyed.


In service specific logs I have no errors/warnings. It looks to me as
if the actual service did not even start executing.

Could you give me some hints why JDWP stopped working with new Commons
Daemon release? I cannot go back to previous (1.0.2) release because
it does not work on Windows 7.


Thanks for any hints or help.

Best regards,
Chris M. Wilk
