**Test Count**: 11 tests

**Key Scenarios**:
- ✅ Validates non-null streams
- ✅ Throws CrawlerSystemException for null
- ✅ Called during getText execution
- ✅ Does not consume or modify stream
- ✅ Consistent behavior across multiple calls
- ✅ Works with various InputStream types

### 5. TextExtractorEnhancedTest.java
**Purpose**: Test TextExtractor improvements and encoding handling.

**Key Test Areas**:

		{"SHØRT", 49},
		{"There are far too many object names, and far too few bucket names!", 8},
		{"a/b/c/", 159},
		{"/a/b/c", 96},
		{string([]byte{0xff, 0xfe, 0xfd}), 147},
	}

	// Tests hashing order to be consistent.
	for i, testCase := range testCases {
		if sipHashElement := hashKey("SIPMOD", testCase.objectName, 200, testUUID); sipHashElement != testCase.sipHash {

        assertEquals(0, DialectVersion.SMB302.compareTo(DialectVersion.SMB302));
    }

    @Test
    @DisplayName("Should return consistent ordinal values")
    void testOrdinalValues() {
        // Ordinal values should be consistent with enum declaration order
        assertTrue(DialectVersion.SMB1.ordinal() < DialectVersion.SMB202.ordinal());

it is unlikely that we'll be able to remove `null` entirely.

After migrating to Java 8, we can use pluggable type checkers to ensure that our annotations are consistent, 
and there are no missing null checks.

## Decision

Use "NullAway" in JSpecify mode to check for null-related errors in Java code.
