Facing a strange issue while reading a pdf using pdfreader.(itext)
PdfReader reader = PdfReader(bytearray).
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOf(Arrays.java:3236) at java.io.ByteArrayOutputStream.grow(ByteArrayOutputStream.java:118) at java.io.ByteArrayOutputStream.ensureCapacity(ByteArrayOutputStream.java:93) at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:153) at com.itextpdf.text.pdf.PdfReader.FlateDecode(PdfReader.java:2071) at com.itextpdf.text.pdf.PdfReader.FlateDecode(PdfReader.java:1926) at com.itextpdf.text.pdf.FilterHandlers$Filter_FLATEDECODE.decode(FilterHandlers.java:108) at com.itextpdf.text.pdf.PdfReader.decodeBytes(PdfReader.java:2476) at com.itextpdf.text.pdf.PdfReader.decodeBytes(PdfReader.java:2424) at com.itextpdf.text.pdf.PdfReader.getStreamBytes(PdfReader.java:2489) at com.itextpdf.text.pdf.PdfReader.readObjStm(PdfReader.java:1430) at com.itextpdf.text.pdf.PdfReader.readDocObj(PdfReader.java:1365) at com.itextpdf.text.pdf.PdfReader.readPdf(PdfReader.java:672) at com.itextpdf.text.pdf.PdfReader.(PdfReader.java:181) at com.itextpdf.text.pdf.PdfReader.(PdfReader.java:250) at com.itextpdf.text.pdf.PdfReader.(PdfReader.java:240)

To convert my comment into an answer since the OP said it helped solve the problem:
Increase the heap with -Xmx1500m (or even to -Xmx2048m).
One side note: Why do you use such a huge code cache size? You can easily half that -XX:ReservedCodeCacheSize=512m (or even more -XX:ReservedCodeCacheSize=256m). To get an impression start on what you really need you can use jconsole and select code cache section.
