### Apache Hop version? 2.18.0-SNAPSHOT ### Java version? OpenJDK 21 ### Operating system Linux ### What happened? In a rare scenario when converting Strings to Timestamps (with ns precision) in 2 transform copies of the Select Values transform I get: ``` 2026/04/27 09:44:48 [Error] to timestamp.0 - Unexpected error 2026/04/27 09:44:48 [Error] to timestamp.0 - org.apache.hop.core.exception.HopConversionException: 2026/04/27 09:44:48 [Error] to timestamp.0 - 2026/04/27 09:44:48 [Error] to timestamp.0 - Error converting value event_timestamp_str to type Timestamp with source value: [2025/03/03 10:01:19.899750000] 2026/04/27 09:44:48 [Error] to timestamp.0 - Index 15 out of bounds for length 13 2026/04/27 09:44:48 [Error] to timestamp.0 - 2026/04/27 09:44:48 [Error] to timestamp.0 - 2026/04/27 09:44:48 [Error] to timestamp.0 - at org.apache.hop.pipeline.transforms.selectvalues.SelectValues.metadataValues(SelectValues.java:390) 2026/04/27 09:44:48 [Error] to timestamp.0 - at org.apache.hop.pipeline.transforms.selectvalues.SelectValues.processRow(SelectValues.java:439) 2026/04/27 09:44:48 [Error] to timestamp.0 - at org.apache.hop.pipeline.transform.RunThread.run(RunThread.java:54) 2026/04/27 09:44:48 [Error] to timestamp.0 - at java.base/java.lang.Thread.run(Thread.java:1583) ``` This is caused by the 2 copies (somehow!) using the same `SimpleDateFormat` object. The situation occured when reading with a `Text File Input` transform with an epoch timestamp (2 copies), then building a String with JavaScript (2 copies) and then the Select Values (2 copies) with the error. ### Issue Priority Priority: 2 ### Issue Component Component: Transforms -- This is an automated message from the Apache Git Service.
