[GH] (poi/inputstream-fixes): Workflow run "Java CI with Gradle" failed!
The GitHub Actions job "Java CI with Gradle" on poi.git/inputstream-fixes has failed.
Run started by GitHub user pjfanning (triggered by pjfanning).
Head commit for run:

Fix bugs, locking and per-call allocations in POI's input streams
Bugs:
- RLEDecompressingInputStream.skip over-skipped when spanning chunks and
returned -1 / n instead of the bytes skipped
- RecordInputStream.readPlain ignored off/len
- ReplacingInputStream compared signed pattern bytes to read()'s 0..255 and
returned negative values for replacement bytes >= 0x80; skip and mark/reset
bypassed the replacement state
- ContinuableRecordInput.readShort/readDouble did not roll over CONTINUE
records like the other reads
- LittleEndianByteArrayInputStream.setReadIndex rejected the end position
- ZipArchiveThresholdInputStream.skip returned -1 at the end of the stream
Locking:
- LittleEndianInputStream / ChunkedCipherInputStream: drop synchronized
from mark/reset (reads were never locked)
- CryptoAPIDocumentInputStream: seek/setBlock lock like read does
Performance:
- LittleEndianInputStream: primitive reads use a reused buffer and readFully
(also fixes false EOF on short reads), read()/skip() keep readIndex
right, skipFully reuses a skip buffer
- ChunkedCipherInputStream: read() without allocating, skipFully moves the
position instead of decrypting the skipped chunks
- LittleEndianByteArrayInputStream: advance pos directly instead of the
synchronized ByteArrayInputStream.skip/read
- XSSFVMLDrawing buffers the stream under the byte-wise ReplacingInputStream
- ZipHelper uses commons-io CloseShieldInputStream instead of
NoCloseInputStream
