Why String.getBytes() throws BufferOverflowException exception?

Question

the following is my codes:
String gbStr = new String(s_content.getBytes(),"ISO_8859_1");
but sometimes it throws exception like this:
java.nio.BufferOverflowException
at java.nio.charset.CoderResult.throwException(CoderResult.java:259)
at java.lang.StringCoding$CharsetSE.encode(StringCoding.java:338)
at java.lang.StringCoding.encode(StringCoding.java:372)
at java.lang.StringCoding.encode(StringCoding.java:378)
at java.lang.String.getBytes(String.java:608)
why?

Answer 1

One explaination offered is
We took a look at the source code of the JVM. The
problem stems from the fact that float values are used
to indicate the maximum value of bytes per characters
in java.nio.charset.CharsetEncoder.maxBytesPerChar.
The issue is that floats cannot accuratly hold more than
2^24 integer values which is equals to 16,777,216.
After that value is reached, the encoding operation in
the character set classes incorrectly rounds down the
amount of memory needed for the buffer. The correct
solution would be to use doubles instead, or account
for the round off problem by increasing the buffer size.
SUGGESTED WORKAROUND
The workaround that we are using, is to use to .
getBytes() on a substring that is smaller than 16MB,
and combined the results by either using a
ByteArrayOutputStream or a ByteBuffer.
NOTE: If you are planning on using more than one-byte
characters sets, than you have to make sure that your
buffer is set accordingly.
