Hi Jim,

Given the infrequency of the exception messages being used,
can we simplify them and/or reuse the strings?

The stack trace would usually show what API was being used so I would simplfy the messages to:
     "exceeds implementation limit" or "size exceeds implementation limit".
   UnsyncByteArrayOutputStream: 49, 61, 73
   UnsyncByteArrayOutputStream:247
   AbstractStringBuilder:269

The message are not typically sentences so omit the final ".".
   String.java: 3576, (I know it was there before),

Unsafe.java:632  "Not able to allocate"   -> "Unable to allocate".
Isn't the "bytes of native memory" redundant with the function of allocateMemory? (and can be omitted). Ditto in reallocate, the allocate/reallocate is obvious from the stack trace.

Thanks, Roger

"Unable to allocate buffer" seems vague in the context of an OOME.  If
the problem is trying to create a too-large array, maybe something like,
"Buffer for \\Q...\\E sequence would exceed maximum array size".
A generic message that does not necessarily expose the use of an
internal array seems best, e.g.

"... exceeds implementation limits"
