Unexpected end of zlib input stream как исправить

[{«Product»:{«code»:»SS3RA7″,»label»:»IBM SPSS Modeler»},»Business Unit»:{«code»:»BU059″,»label»:»IBM Software w/o TPS»},»Component»:»Modeler»,»Platform»:[{«code»:»PF033″,»label»:»Windows»}],»Version»:»Not Applicable»,»Edition»:»All Editions;Workstation»,»Line of Business»:{«code»:»LOB10″,»label»:»Data and AI»}}]

I get a Unexpected end of ZLIB input stream error when I try to read a model, I committed before. I have tried the SingleCheckinAndDownload.java example and the error occurs to. After a commit the 3D-view in bimviews does also not work. There is only the loading project bar but without progress. Is there something wrong with my code or is there a problem with the server?

Error :

The corresponding source code is as follows:

InputStream is = ...
int available = is.available();
byte[] fileBytes = new byte[available];
int read = is.read(fileBytes);

The file fails to create a file based on fileBytes. The above error is reported.

Troubleshoot

There is no problem when verifying locally. I checked it online and said that the stream object is not closed and the reading is incomplete.
Checked the code, the input stream did not close. As an old driver, he condemned himself.
But with the stream closing action added, the problem remains.

Added log information output:

InputStream is = ...
int available = is.available();
byte[] fileBytes = new byte[available];
int read = is.read(fileBytes);
log.info("read:" + read + ", available:" + available);

Local execution, ok, read and available are consistent.
The test environment runs, and the print log is as follows: read:9608, available:54192
Why the content read is not the same as the available, check the comment of the read method in the InputStream.
The method returns the actual read length, and it is possible to read the length of the byte array at most. Instead of thinking that I must read the length of the byte array.

Modified the read code, the problem is solved

import org.apache.commons.io.IOUtils;
...

byte[] fileBytes = IOUtils.toByteArray(is);

The tool class implementation principle is as follows ():

byte[] buffer = new byte[1024];
int len = 0;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
while((len = inputStream.read(buffer)) != -1) {
     bos.write(buffer, 0, len);
}
bos.close();
return bos.toByteArray();

Why is this problem?

A brief review of the operating system content, understand as follows:
Operating system content has segmental, page-based memory management. Memory is more expensive than cheaper disks. When the operating system loads content from external to memory, it is not necessary to load everything into memory.
Otherwise, if the application size is larger than the memory, it will not be executed.
For example, page memory management, allocate space by page, load page by file when accessing file, if it can directly hit, return hit content, otherwise it will generate page fault interrupt and read from disk again.
The server we deployed is a Linux virtual machine. I guess the access disk is directly accessed by my local physical machine. There are more levels of IO mapping, and there is a gap in the reading process.
gets the first part of the content, not all of it.

Understand the fur, it is rough. Interested students can turn over the memory management and IO principles of the operating system.

Attached, source code comments for the InputStream.read method (jdk1.8)

/**
 ... Slightly, see the method annotation below
 */
public int read(byte b[]) throws IOException {
    return read(b, 0, b.length);
}

/**
 * Reads up to <code>len</code> bytes of data from the input stream into
 * an array of bytes.  An attempt is made to read as many as
 * <code>len</code> bytes, but a smaller number may be read.
 * The number of bytes actually read is returned as an integer.
 *
 * <p> This method blocks until input data is available, end of file is
 * detected, or an exception is thrown.
 *
 * <p> If <code>len</code> is zero, then no bytes are read and
 * <code>0</code> is returned; otherwise, there is an attempt to read at
 * least one byte. If no byte is available because the stream is at end of
 * file, the value <code>-1</code> is returned; otherwise, at least one
 * byte is read and stored into <code>b</code>.
 *
   Note the following paragraph, assuming k is the actual number of bytes read, the content read will be filled to b[off] to b[off+k-1], b[off+k] to b[off +len-1]maintained
 * <p> The first byte read is stored into element <code>b[off]</code>, the
 * next one into <code>b[off+1]</code>, and so on. The number of bytes read
 * is, at most, equal to <code>len</code>. Let <i>k</i> be the number of
 * bytes actually read; these bytes will be stored in elements
 * <code>b[off]</code> through <code>b[off+</code><i>k</i><code>-1]</code>,
 * leaving elements <code>b[off+</code><i>k</i><code>]</code> through
 * <code>b[off+len-1]</code> unaffected.
 *
 * <p> In every case, elements <code>b[0]</code> through
 * <code>b[off]</code> and elements <code>b[off+len]</code> through
 * <code>b[b.length-1]</code> are unaffected.
 *
 * <p> The <code>read(b,</code> <code>off,</code> <code>len)</code> method
 * for class <code>InputStream</code> simply calls the method
 * <code>read()</code> repeatedly. If the first such call results in an
 * <code>IOException</code>, that exception is returned from the call to
 * the <code>read(b,</code> <code>off,</code> <code>len)</code> method.  If
 * any subsequent call to <code>read()</code> results in a
 * <code>IOException</code>, the exception is caught and treated as if it
 * were end of file; the bytes read up to that point are stored into
 * <code>b</code> and the number of bytes read before the exception
 * occurred is returned. The default implementation of this method blocks
 * until the requested amount of input data <code>len</code> has been read,
 * end of file is detected, or an exception is thrown. Subclasses are encouraged
 * to provide a more efficient implementation of this method.
 *
 * @param      b     the buffer into which the data is read.
 * @param      off   the start offset in array <code>b</code>
 *                   at which the data is written.
   * @param len the maximum number of bytes to read. --- Read most len
 * @return     the total number of bytes read into the buffer, or
 *             <code>-1</code> if there is no more data because the end of
   * the stream has been reached. --- The length of the actual read
 * @exception  IOException If the first byte cannot be read for any reason
 * other than end of file, or if the input stream has been closed, or if
 * some other I/O error occurs.
 * @exception  NullPointerException If <code>b</code> is <code>null</code>.
 * @exception  IndexOutOfBoundsException If <code>off</code> is negative,
 * <code>len</code> is negative, or <code>len</code> is greater than
 * <code>b.length - off</code>
