JVM 21 LTS is now out. So I decided to try to building Daffodil using it. My WIP PR is https://github.com/apache/daffodil/pull/1090
It looks pretty close. The --release 8 option for javac is now deprecated. So I conditionalized that. Fixed some deprecated calls. Remaining issues: 2 more deprecated calls (hence fatal warnings turned off for now) 5 tests fail. One each in these 3 test classes org.apache.daffodil.TresysTests.test_BG000 org.apache.daffodil.section13.text_number_props.TestTextNumberProps.test_textNumberPattern_exponent01 org.apache.daffodil.section05.simple_types.TestSimpleTypes.test_double_binary_06 All 3 of those failures are floating point related like this: (highlighted digit isn't output any more) [error] Expected (attributes stripped) [error] <d_02>9.8765432109876544E16</d_02> [error] Actual (attributes ignored for diff) [error] <ex:d_02>9.876543210987654E16</ex:d_02> The Expected has one more digit 4 at the end. 1 other test failure is for reasons unknown. Possible change in regex behavior? org.apache.daffodil.io.layers.TestJavaIOStreams.testBase64ScanningForDelimiter1 One CLI test failure: org.apache.daffodil.cli.cliTest.TestEXIEncodeDecode.test_CLI_Encode_Decode_EXI
