I noticed the math problem in jdk.internal.classfile.impl.EntryMap::nextPowerOfTwo:

% jshell
| Welcome to JShell -- Version 19.0.2
| For an introduction type: /help intro

jshell> public static long nextPowerOfTwo( long x ) {
   ...> x = -1 >>> Long.numberOfLeadingZeros(x - 1);
   ...> return x + 1;
   ...> }
| created method nextPowerOfTwo(long)

jshell> nextPowerOfTwo(0)
$2 ==> 0

jshell> nextPowerOfTwo(1)
$3 ==> 0

jshell> nextPowerOfTwo(2)
$4 ==> 2

jshell> nextPowerOfTwo(3)
$5 ==> 4

Note how "1" yields "0" as the next power of two.

Also check if you really need "next" power of two, which should give next(2) = 4. Maybe this is just "round"?
