Andrew McIntyre commented on DERBY-1078: ---------------------------------------- Sanity check on j9, jdk13, and jdk142 look good. Committed derby-1078.diff to trunk with revision 395458. Rick, please resolve and/or close if this takes care of this issue. > Be able to build Derby when JAVA_HOME is set 1.6 > ------------------------------------------------ > > Key: DERBY-1078 > URL: http://issues.apache.org/jira/browse/DERBY-1078 > Project: Derby > Type: Improvement > Components: Build tools > Versions: 10.2.0.0 > Reporter: Rick Hillegas > Fix For: 10.3.0.0 > Attachments: derby-1078.diff > > 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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
