Java Compiler Issue for version 1.2

[Ashik Uzzaman]

In my Linux RedHat Enterprise 4.7/Tomcat 6/JDK 1.5.0.20 environment, I am seeing an error at runtime from my webapplication that tries to compile some java rules in XML file. I only have JDK 1.5 installed in my machine which I have indicated in ,.bash_profile as JAVA_HOME so that I don't use any other variable by mistake. Redhat installation came with JDK 1.4 whih I am not using. However, I don't know how come 1.2 is coming as per the log below. When I look at my ant build file, I see there are couple of eclipse related target, but those doidn't seem to be vulnerable to me. I don't have Eclipse installed and hence there should be no side effect of that.

Any idea if I am missing something very obvious?

I don't know what the "RuleCompiler" is, but it seems to pass some flags that the Java compiler doesn't understand. Do the docs of the RuleCompiler say anything about configuration?
