    jzlib 1.0.7: ArrayOutOfBoundException in ZOutputStream.write()

    I have a simple test case producing a sure ArrayOutOfBoundException in jzlib 1.0.7 depending on the data subsequently written to one and the same instance of ZOutputStream.

    Stacktrace:

    java.lang.ArrayIndexOutOfBoundsException: 587
    at com.jcraft.jzlib.Tree.d_code(Tree.java:149)
    at com.jcraft.jzlib.Deflate.compress_block(Deflate.java:691)
    at com.jcraft.jzlib.Deflate._tr_flush_block(Deflate.java:897)
    at com.jcraft.jzlib.Deflate.flush_block_only(Deflate.java:772)
    at com.jcraft.jzlib.Deflate.deflate_slow(Deflate.java:1195)
    at com.jcraft.jzlib.Deflate.deflate(Deflate.java:1567)
    at com.jcraft.jzlib.ZStream.deflate(ZStream.java:133)
    at com.jcraft.jzlib.ZOutputStream.write(ZOutputStream.java:102)
    at com.jcraft.jzlib.JZLibTestCase.main(JZLibTestCase.java:51)
    at JZLibTestCase.main(JZLibTestCase.java:28)

    The problem occurs very rarely and depends on the data subsequentially written to an open ZOutputStream from jzlib.

    Do you have a hint how to fix this? Have you ever heard of this?
