False positive for NON_STATIC_PATTERN_COMPILE_CALL

[boris-petrov]

I have something like:

public final class RegexHelpers {
	private RegexHelpers() {
	}

	public static Pattern getUnescapedSymbolPattern(char symbol) {
		return Pattern.compile(getUnescapedSymbolRegex(symbol));
	}

	public static String getUnescapedSymbolRegex(char symbol) {
		String escapedSymbol = Pattern.quote(String.valueOf(symbol));
		return "(^|[^\\\\])(\\\\\\\\)*" + escapedSymbol; // (^|[^\\])(\\\\)*,
	}
}

Which gives a NON_STATIC_PATTERN_COMPILE_CALL.

I also have another case of a false positive in code like:

	private boolean propertyMatchesText(String test, String text, boolean shouldMatchWholeString) {
		String pcre = SomeHelpers.textToPcre(text, shouldMatchWholeString);
		int caseInsensitiveFlag = isCaseInsensitive() ? Pattern.CASE_INSENSITIVE : 0;
		Pattern pattern = Pattern.compile(pcre, caseInsensitiveFlag | Pattern.UNICODE_CASE);
		return pattern.matcher(test).find();
	}
