| ant javac version question | ant javac version question 2006-12-11 - By glenn opdycke-hansen
Right, I know that jdk 1.4.2 works.
I suspect that some other jdk version is creeping into the class/jar file.
I specified JAVA_HOME for the 1.4.2 jdk. I also suggested to the
developer to change the path. (I heard that that did not work)
java -version also states that 1.4.2 will be used.
Is there some option/parm on the javac that will help with this?
Perhaps <target="1.4"> ?
Perhaps <compiler="modern"> ?
