ZipFile doesn't chunk entries correctly

[Chocohead]

Noticed this when trying to read zip entries by their declared size:

try (ZipOutputStream zip = new ZipOutputStream(new FileOutputStream("test.zip"))) {
	zip.putNextEntry(new ZipEntry("example"));
	byte[] in = new byte[3000]; //Just something bigger than the 2048 buffer TInputStream uses
	Arrays.fill(in, (byte) 1);
	zip.write(in);
}

try (ZipFile zip = new ZipFile("test.zip")) {
	ZipEntry entry = zip.getEntry("example");
	byte[] read;
	try (InputStream in = zip.getInputStream(entry)) {
		read = stream.readNBytes((int) entry.getSize());
	}
	assert read.length == 3000;
}

When run as JavaScript at least, I get the following crash....

Exception in thread "main" java.io.EOFException
	at org.teavm.classlib.java.util.zip.TInflaterInputStream.read(TInflaterInputStream.java:106)
	at org.teavm.classlib.java.util.zip.TZipFile$ZipInflaterInputStream.read(TZipFile.java:331)
	at org.teavm.classlib.java.io.TInputStream.readNBytes(TInputStream.java:108)
	at com.chocohead.Example.main(Example.java:46)

Interestingly enough, using a ZipInputStream works fine:

try (ZipInputStream zip = new ZipInputStream(new FileInputStream("test.zip"))) {
	zip.getNextEntry();
	byte[] read = zip.readNBytes(3000);
	assert read.length == 3000;
}
