If someone is doing a partial build (without langtools) the import jdk is used for javac compilation, not the boot jdk javac. This has not changed. The boot jdk javac is only used to build langtools and the hotspot serviceability agent.

Hi Jon,

For a long time now, the JDK 8 langtools repo has accepted -source 8 and -target 8, so this should not affect which version of langtools you need to use. Of course, you do need to make sure that these options are not used with the bootstrap javac, which will typically be from JDK 7. That wasn't quite my query/concern - I wasn't very clear. If someone is doing a partial build, ie JDK repo only, they will now have to use a JDK8 boot JDK (or point to suitable langtools import?) - correct? (Where a full build would use the current langtools to build the rest of the JDK.) Just trying to understand if there may be places (JPRT?) where we've so far been able to use a JDK7 boot JDK but will no longer be able to. Thanks, David -- Jon

Please review changes to rev up the default -source and -target for jdk compilation, thus producing v52.0 class files. Bug is here: https://jbs.oracle.com/bugs/browse/JDK-8001191 Webrev is here: http://cr.openjdk.java.net/~ksrini/8001191/webrev.0/ Note: this webrev is generated against the master repository but changes will be pushed via tl after the tl-master sync is completed.
