Andy Jefferson edited comment on JDO-749 at 11/14/15 10:37 AM: --------------------------------------------------------------- Actually, after doing a few tests with Java7 and Java8, we cannot simply add Java8 related classes to jdo-api compile to 1.8 and run with 1.7, since some operations have a check on major.minor version and it finds the jdo-api with major.minor as 52.0. Ways around this are 1. Have 2 jdo-api jars. One for java7 and one for java8 (with the java.time support), and the user pulls in the one they require. 2. Just move to java8 minimum Note : this applies solely to the use of Java8 types in the JDOQLTypedQuery. Java8 types can still be used with JDO 3.2 without any change to "jdo-api" for all other features (persistence, standard JDOQL). was (Author: andy): Actually, after doing a few tests with Java7 and Java8, we cannot simply add Java8 related classes to jdo-api compile to 1.8 and run with 1.7, since some operations have a check on major.minor version and it finds the jdo-api with major.minor as 52.0.
