Eric, I have encountered this issue before. I am not sure what I did to fix it. I think I used ecj instead of the Apple javac. Check the javac perl script that IcedTea has. The other option is to apply this patch in the required build files.
http://cr.openjdk.java.net/~andrew/ecj/01/webrev.01/make/build.xml.udiff.html Here is my initial post on this http://mail.openjdk.java.net/pipermail/distro-pkg-dev/2009-August/006857.html If I remember correctly, there is a tool that is compiled by ant (the two in the output), but it is not compiled with Java 5 byte code. When ant tries to run the tool you get that error. I would switch to using ecj, as you might be able to get past this issue, there is another issue that will come up and ecj acts differently than javac and you really need the ecj way of doing things. This is my original email on this: http://mail.openjdk.java.net/pipermail/distro-pkg-dev/2009-August/006879.html Michael On Sat, Nov 14, 2009 at 11:48 PM, Eric Richardson <ekrichard...@gmail.com>wrote: > > -def-pcompile: > [mkdir] Created dir: > /Users/eric/openjdk/icedtea/openjdk-boot/build/bsd-ppc/langtools/build/toolclasses > [javac] Compiling 2 source files to > /Users/eric/openjdk/icedtea/openjdk-boot/build/bsd-ppc/langtools/build/toolclasses > > BUILD FAILED > /Users/eric/openjdk/icedtea/openjdk-boot/langtools/make/build.xml:603: > java.lang.UnsupportedClassVersionError: Bad version number in .class file > >
