Category: Compiler integration Group: 3: Ugly Status: Open Resolution: None Priority: 5 Submitted By: Dan Smith (dlsmith) Assigned to: Nobody/Anonymous (nobody) Summary: Broken 1.4 compiler when running under 5.0 Initial Comment: See support request [ 1462794 ]. Apparently, when DrJava is run under Java 5.0, the user is allowed to choose the Java 1.4 version of tools.jar; in doing so, they create an inconsistent state in which the compiler will run, but will produce "class file has wrong version" errors pointing to the 5.0 APIs. Correct behavior would be one of: - Only allow a Java 5.0 compiler to be defined when running under Java 5.0; only allow a Java 1.4 compiler to be defined when running under Java 1.4. Continue using the "current" APIs as the bootclasspath. - Allow both a Java 5.0 compiler and a Java 1.4 compiler to be defined, regardless of the JVM used to run DrJava. Compile with a bootclasspath corresponding to the tools.jar file. To avoid confusion, note that there are 4 "classpaths" involved in compilation: 1) Compilation bootclasspath: The path to search for essential classes referenced in the sources. 2) Compilation classpath: Additional path to search for classes referenced in the sources. 3) Compiler JVM bootclasspath: The path to search for essential classes when running the compiler. 4) Compiler JVM classpath: Additional path to search for classes required when running the compiler. Compiler runtime classes are found by searching the path 3:4. Compile- time classes referenced in the sources are found by searching the path 1:2. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=438935&aid=1463741&group_id=44253 |
