--------------------------------------------
I've filed a bug on eclipse ECJ compiler requesting a change in the way how it searches for boot classes. The bug URL in eclipse bugzilla is https://bugs.eclipse.org/bugs/show_bug.cgi?id=188648

-------------------------------------
Sorry, I mean the problem was with Eclipse 3.1.1. It was resolved by using Eclipse 3.1.2.

-------------------------------------
I noticed sometimes similar problem with Eclipse 3.2.1 on Linux. It seems that in this case Eclipse does not see jre/bin/default/kernel.jar library and include it into list of system libraries and this leads to a compilation problem.

Gregory Shimansky commented on HARMONY-3565:
--------------------------------------------
Confirmed. The build for classlib specifies -classpath for all harmony jar files. Build for jdktools doesn't. So I think the failure to find j.l.Object is somewhere in finding necessary jar files from bootclasspath property. The bug is not intermittent.

[jira] Updated: (HARMONY-3565) [testing][eclipse] eclipse
intermittently failed to compile "Hello world" class
Posted by "Gregory Shimansky (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HARMONY-3565?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Gregory Shimansky updated HARMONY-3565:
---------------------------------------
Assignee: Gregory Shimansky
Trying to reproduce the problem I found out that running ecj as java -jar ecj.jar <some class> always gives an error that j.l.Object cannot be resolved. Specifying harmony boot classes explicitly with -bootclasspath for compiler makes it successfully compile the class.
Looking at CC reports I see that all self hosting errors come from building working_jdktools classes. For me the failure to find j.l.Object class is not intermittent. It is either an error in 100% cases or it doesn't exist. I suspect that ecj just doesn't correctly understand harmony java.boot.class.path property to find necessary jar files.

--------------------------------------------
Since the bug in eclipse is fixed and self-hosting jdktools build scripts were updated to supply bootclasspath explicitly I am inclined to close this bug. What do you think?

Wayne Beaton commented on HARMONY-3565:
---------------------------------------
I'm seeing the same problem on Ubuntu Linux. I'm running Harmony (April 18) on Eclipse 3.2.2.
The environment starts up, but the JRE is missing all but one of the "JRE System Libraries" (on the "Installed JREs" preference page). The one JAR that does appear is bcprov.jar.
I'll see if the stack trace is at all helpful sometime tomorrow.
Here's what's in the log.

[jira] Commented: (HARMONY-3565) [testing][eclipse] eclipse
intermittently failed to compile "Hello world" class
Posted by "Gregory Shimansky (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HARMONY-3565?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12497869 ]
Gregory Shimansky commented on HARMONY-3565:
--------------------------------------------
I found the problem why ecj.jar cannot find boot classes. It tried to create bootclasspath based on java.home/lib directory trying to find all JAR file in this directory. On Sun it works ok because all boot classes are located in java.home/lib directory.
On harmony boot classes are located in java.home/bin/default/kernel.jar and in java.home/lib/boot. Eclipse ecj doesn't try to look for such JAR files. It also doesn't try to use somewhat undocumented sun.boot.library.path property which DRLVM defines for compatibility.
The problem is reproducible both on IBM VME and DRLVM because boot classes layout is the same for both of them.
The code which does bootclasspath handling for ECJ is here: http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.jdt.core/batch/org/eclipse/jdt/internal/compiler/batch/Main.java?view=markup
Look at the function getLibrariesFiles, it filters the directory for any file which has *.jar name and collects them into paths array. This function is called from handleBootclasspath with an array directoriesToCheck which contains java.home/lib directory name.
I think that ECJ uses not quite correct heuristics to find boot classes. It could at least try to check sun.boot.class.path property in addition to collecting *.jar files in java.home/lib. Eclipse SDK does such thing when it tries to detect JRE properties. So I think we could ask Eclipse community to fix ECJ by filing a bug on Eclipse.
