Johnny Wu commented on XERCESJ-784:
-----------------------------------
I just downloaded Xeres2 for Mac OS and got the same error during compilation.
Can anyone confirm this problem was resolved for Mac? Thanks!

> file:/home/download/cvs/xml-xerces/java/build.xml:232: Compile failed; see the

>
> Total time: 31 seconds
> Problem:
> Blackdown JDK rt.jar has older versions of org.apache.* in it causing the
> compiler to pick the class and interface definitions from there, rather than
> the
> current compiled source directory. Setting -Xbootclasspath did not help.
> Possible Solution:
> After some digging around, I found that the build is correcting
> the problem in tools/src/XJavac.java by resetting the bootclasspath
> based on the type of JDK being used to do the build. Based on the information
> it extracts from the "java.vendor" environment variable, it sets the correct
> bootclasspath before launching the original javac compiler. Currently it is
> testing for only two JDK environments, IBM and Sun. Blackdown JDK 1.4.1 also
> requires the the bootclasspath to be changed to avoid the classes conflict.
> I changed XJavac.java to add the case for Blackdown, recompiled and repackaged
> xjavac.jar and the build went through without a hitch.
> Here is what the Blackdown Linux JDK sets java.vendor to:
> java.vendor=Blackdown Java-Linux Team
> Changed line 134 in XJavac.java to:
> else if ( (vendor.indexOf("SUN") >= 0) || (vendor.indexOf("BLACKDOWN") >= 0))
