[drlvm][EUT] org.eclipse.jdt.core.tests.model.ClasspathTests.testEncoding cannot remove unicode

                 Key: HARMONY-4493
                 URL: https://issues.apache.org/jira/browse/HARMONY-4493
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
         Environment: Linux/ia32
            Reporter: Ilya Berezhniuk
            Priority: Minor

Test org.eclipse.jdt.core.tests.model.ClasspathTests.testEncoding creates directory with unicode
name in its project directory. Then it removes project, it involves removing underlying files
and directories.

When executing on DRLVM, it cannot remove unicode directory and therefore the whole project,
and then tries 60 times with 1 second delay. So test goes 1 minute, and all remaining tests
in ClasspathTests suite also execute 1 minute.

Although debugging under Eclipse is now unstable on DRLVM/Linux (it often crashes with SIGSEGV
when using single stepping), I've got some results using breakpoints.

Looks like the problem is somewhere in enumerating subdirectories of project dir "P". Eclipse
uses org.eclipse.core.internal.localstore.UnifiedTree to enumerate subitems in project folder:
accept(IUnifiedTreeVisitor, int) calls addNodeChildrenToQueue to fill queue with subitems.
But when queue is filled, it contains incorrect path to unicode directory. Directory is named
"src\u3400", but queue item for this directory contains path from 6 to 8 chars and named as
"srcXXXXX", where XXXXX can be various characters including space.

I cannot determine a cause of this error certainly - so bug is now tagged as [drlvm]. I'll
try to go forward and investigate bug deeper.
