Hi Antonio, I am just trying to understand what is done in EclipseJavaCompiler ;)
Original code: if we have the compiler-compliance-level parameter set to 1.5, then the JDT options org.eclipse.jdt.core.compiler.compliance and org.eclipse.jdt.core.compiler.source are set to 1.5. Then SystemUtils.JAVA_VERSION_INT is used to set the JDT option org.eclipse.jdt.core.compiler.codegen.targetPlatform. So if I use a 1.6 JVM and if I set compiler-compliance-level to 1.5 (maximum handled by JDT 3.1) then I end up with the following combination out of EclipseJavaCompiler: - compliance = 1.5 - source = 1.5 - targetPlatform = 1.3 It is true that this combination is discouraged in the Eclipse Preferences panel. It requires that Source compatibility <= Classfile compatibility (targetPlatform) <= Compliance level. But with my "wrong" configuration I get no errors from JDT and XSPs are compiled and are running correctly (which is "understandable" because my target platform is a 1.6, so the minimum level of 1.3 is respected). Anyway I think that EclipseJavaCompiler should be modified to properly handle 1.6 without reverting to 1.3 by default (even if the 2 additional jdt properties look more cosmetic than critical for the generated code).

I am wondering about your message, because IIRC, the compliance level almost define the target java version for compiled class. I mean if I select compliance level 1.5, the generated class cannot be compiled for java 1.3 because 1.3 JVM cannot handle some of the new features introduced in java 1.5. I can be wrong be I can recall it is not possible to set that way in eclipse. I mean a higher compliance level (ie: 1.5) and a lower compilation level (ie: 1.3). It simply does not work.
