Hi, Sho is right. Java 1.7 is not required. But you have to be careful. If jars produced by 1.7 are loaded by an older compiler, then you will get a version mismatch error at runtime. So the target should still be 1.6 even if you are using the 1.7 JDK. The Oracle JDK compilers are able to produce jars compatible with prior releases if configured correctly, but by default the jars will NOT be backward compatible. I actually do use the 1.7 compiler for deployments, but the lcsim-parent POM that governs shared settings of lcsim-based projects is able to produce 1.6 compatible jars via a setting in the POM file. --Jeremy -----Original Message----- From: [log in to unmask] [mailto:[log in to unmask]] On Behalf Of Sho Uemura Sent: Thursday, September 05, 2013 12:39 PM To: Hansson Adrian, Per Ola Cc: Kyle McCarty; hps-software Subject: Re: hps-java Error 1.7 is recommended in general because 1.6 is insecure and no longer supported by Oracle, but there's nothing in hps-java/lcsim that requires 1.7. And some people are still stuck with 1.6 on centrally managed systems. So 1.7 is not required.
