Re: [xmlblaster] memory leak? FIXED

[Marcel Ruff <ruff at swand.lake.de>]

Hi 刘 文

thanks for reporting this bug.
It is fixed now and available with CVS.
Could you please confirm that the problem disappeared?

best regards,

Marcel

PS: Remove all files in
xmlBlaster/src/java/org/xmlBlaster/engine/admin/extern/snmp
after cvs update, they currently don't compile.
