resetConnectionPoolMaxSize resets the core pool size

[bbottema]

Problem

MailerGenericBuilder.resetConnectionPoolMaxSize() currently delegates to withConnectionPoolCoreSize(DEFAULT_CONNECTIONPOOL_MAX_SIZE).

As a result, calling it changes the core pool size to 4 and leaves the configured maximum unchanged, contrary to the public API contract.

Expected behavior

resetConnectionPoolMaxSize() should restore only the maximum pool size to DEFAULT_CONNECTIONPOOL_MAX_SIZE, leaving the configured core size untouched.

Fixed for v9.1.8. resetConnectionPoolMaxSize() now restores the maximum pool size to its default without changing the configured core size.

For example, a builder configured with core size 2 and max size 12 now retains core size 2 and restores max size 4 after the reset call.

Available in Simple Java Mail 9.1.8. resetConnectionPoolMaxSize() now restores only the maximum pool size and leaves the core size unchanged.
