…test WorkspaceSourceFolderContentProviderTest swapped the singleton logger for a mock throwing on any error() call, without ever restoring it. Depending on the test class execution order (different on Windows CI), later tests such as PluginToolsTest then failed with "error must not get thrown on closed projects" when production code legitimately logged an exception.
…ation The previous test expected resolveClassNameToType to return null on JavaModelException, but that method propagates the exception by design: the catch (and logging) happens in its callers. The new test triggers the failure through superClassChanged() with a mocked package fragment root and asserts that the status is still OK and the error was logged through LogHandler.

Coverage Delta: Improved line/branch coverage for exception handling in MoreUnitWizardPageOne by adding a new test method.
Tested Classes: MoreUnitWizardPageOne, LogHandler
Newly Covered Branches: The JavaModelException catch block in resolveClassNameToType.
Edge Cases Added: Handling of
JavaModelExceptionwhen searching for an IType in a simulated workspace.Rationale for mocking choices: We mock IJavaProject to throw JavaModelException simulating when the workspace project layout causes a search failure. We avoided mocking Eclipse singletons by replacing
JUnitCorePlugin.logwith MoreUnit's natively-testableLogHandler.Eclipse runtime limitations encountered:
JUnitCorePlugin.logandJUnitPlugin.logrely on internal Eclipse Platform active-workspace logging states which throwNullPointerExceptions during headless JUnit 5 tests. Refactored the production code to useorg.moreunit.log.LogHandlerto make testing in Tyco headless mode viable.PR created automatically by Jules for task 7348121160923334048 started by @RoiSoleil
