Savio Fernandes updated VELOCITY-914:
-------------------------------------
Description:
We are using the following method to evaluate string content given a map of
tokens that are used in the localContext of the VelocityEngine.
{noformat}
VelocityEngine :: public boolean evaluate( Context context, Writer out,
String logTag, String instring ){noformat}
which populates the *out* Writer with the evaluated String value.
We have noticed that if the input String contains content similar to :
{noformat}
"<some content> #* <some other content>"{noformat}
The output of the evaluation becomes :
{noformat}
"<some content> "{noformat}
i.e. content after the "#*" part is ignored.
Sample Unit test :
{noformat}
@Test
public void testEmptyString() {
String input = "#* something";
VelocityEngine velocityEngine = new VelocityEngine();
ToolContext toolsContext = new ToolManager().createContext();
toolsContext.put("key", "value");
StringWriter writer = new StringWriter();
velocityEngine.evaluate(toolsContext, writer, "logtag", input);
writer.flush();
String output = writer.toString();
Assert.assertTrue(output != null && output.trim().isEmpty());
}{noformat}
If the '#' character is not followed by '*' character, then the output String
is non-empty.
