Could it be that the target version is set implicitly when explicitly setting
the source version ?
So how about setting the target explicitly, too, as we do in the JSP scripting
budle ?
Eclipse compiler used in commons.compiler causes Illegal type in constant

Key: SLING-1809
URL: https://issues.apache.org/jira/browse/SLING-1809
Project: Sling
Issue Type: Bug
Components: Commons
Affects Versions: Commons Compiler 2.0.0
Reporter: Bertrand Delacretaz
According to [0] the eclipse compiler can't handle enums in certain
environments.
The trunk org.apache.sling.commons.compiler bundle embeds (eclipse-jdt)
core-3.3.0-v_771.jar which exposes this issue.
According to [0] the issue should be fixed in v3.5.2, but the central Maven
repository does not provide a more recent version than the one we currently
use.
To reproduce the problem, install the compiler and java scripting bundle and
create a scripted java servlet that uses enums (example below), at runtime
this causes:
java.lang.VerifyError:
(class: enumtest/EnumTest, method: valueOf signature:
(Ljava/lang/String;)Lenumtest/EnumTest;)
Illegal type in constant pool
[0] https://bugs.eclipse.org/bugs/show_bug.cgi?id=291985
Here's the example servlet, store in
/apps/JavaScriptingTest2/JavaScriptingTest2.java and use JavaScriptingTest2
resource type:
package apps.JavaScriptingTest2;
import javax.servlet.http.*;
import java.io.IOException;
public class JavaScriptingTest2 extends HttpServlet {
static enum EnumTest { FOO, BAR };
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws IOException {
resp.getWriter().write(FOO= + EnumTest.FOO);
}
}

Yes, I think we should set both values - this way we know what is set

i have verified that this issue is solved by
explicitly setting the target version, e.g.
String sourceVersion =
if (sourceVersion != null) {
props.put(org.eclipse.jdt.core.compiler.source, sourceVersion);
props.put(org.eclipse.jdt.core.compiler.compliance,
sourceVersion);
props.put(org.eclipse.jdt.core.compiler.codegen.targetPlatform,
sourceVersion);
}
CompilerOptions settings = new CompilerOptions(props);

the target version is never explicitly set, i.e. it is not related to or
specific to target jsr14.
according to bertrand the issue is easily reproducible.

I don't think we have to upgrade the compiler for this single reason because
the problem is only exhibited when compiling with target jsr14. Since Sling
requires Java 5 there is no use compiling for the jsr14 target and thus this
issues needs not be fixed IMHO.
Note on the jsr14 target: This special (mostly undocumented) target has been
introduced while the new Java 5 language features have been developped. This
target accepts source level for Java 5 but generates Java 1.4 compatible class
files. This is mainly useful for generics, which are not erased anyway. For
Enums and Annotations this target is not really usefull because the Java 1.4
runtime library does not provide the required interfaces like java.lang.Enum.
