I am evaluating Fedora, and i read somewhere the NPTL kernel implemented by Redhat was incompatible with Sun's JDK earlier than 1.4.2. I plan to use Fedora for development, but we have projects that must work with JDK 1.3.1 I have been getting strange compile errors: "compiler message file broken: key=compiler.err.sun.io.MalformedInputException arguments=null, null, null, null, null, null, null I found a fix to this was simply to change the locale: In /etc/sysconfig/i18n ,the line LANG="en_GB.UTF8" to: LANG="en_GB." Will the above cause any other issues? What other incompatibilities should i expect between Java1.3.1 and a NPTL kernel? Has anyone else come across problems with the JDK 1.3.1 or otherwise compiling/running under Fedora?
