Description:
CODE TO REPRODUCE BUG:
{noformat}
System.out.println("\45");
// %
System.out.println(StringEscapeUtils.unescapeJava("\\45"));
// 45, should be %
StringEscapeUtils.unescapeJava("\\uu0030"));
// throws NestableRuntimeException:
{noformat}
This is not compliant with the JLS, which allows both [OctalEscape] and
extraneous u for [UnicodeMarker] in Java string literal.
