java - Is it OK ByteArrayOutputStream is not closed -

i reading following java file: https://svn.apache.org/viewvc/pdfbox/trunk/examples/src/main/java/org/apache/pdfbox/examples/util/printtextlocations.java?revision=1709154&view=co

in linked code, bytearrayoutputstream initialized not closed, ok? in opinion, bytearrayoutputstream closeable, should closed eventually

read javadoc:

closing bytearrayoutputstream has no effect.
