Subject [jira] Commented: (DERBY-1078) Be able to build Derby when JAVA_HOME is set 1.6
Date Sun, 23 Apr 2006 15:35:06 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1078?page=comments#action_12375886 ] 

Knut Anders Hatlen commented on DERBY-1078:
-------------------------------------------

The storerecovery tests have failed a couple of days because the files in java/testing/org/apache/derbyTesting/functionTests/util/corruptio/
are no longer compiled. Added the missing files to functionTests/util/build.xml and committed
revision 396285.

> Currently, the 1.4 compiler is used to build most of Derby. We use the 1.6 compiler to
(optionally) build the JDBC4 support. If you try to build Derby in a shell window with a 1.6
JAVA_HOME, the 1.4 bits will fail to build. This is because those bits do not satisfy the
JDBC4 contract. In addition, even if you could build those bits under 1.6, the 1.6 class files
would fail to load on a 1.4 vm.
> We need to be able to use 1.6 as our default build environment but still generate jar
files which run on 1.4 and 1.5. There may be compiler switches which allow this. If not, building
in a 1.6 environment could fault in the 1.4 compiler as necessary.
