Subject shared class libraries in Maven -Xshare:on
Date Fri, 05 Nov 2004 14:27:03 GMT
Hi, I want to take advantage of JDK 1.5.0's shared class libraries
feature by specifying the -Xshare:on option in the java command line.
To do this I first create the shared class library, then set
MAVEN_OPTS to -Xshare:on and run maven. It fails.
However, if I run a regular java application with sharing turned on, it works. 

Anybody have an idea ? 

Following is my screen dump:

C:\dev\projects\falez-onlineservers-core>java -Xshare:dump

C:\dev\projects\falez-onlineservers-core>java -Xshare:on -jar c:\java\jdk1.5.0\d
