commit

recognize a preview features class (the class minor versopn should be V_PREVIEW) and add a test class

See merge request !174

Resolve "Computing maximum stack size does not work correctly with dead code present"

Closes #317827

See merge request !173

Fix the maxStack computation for methods with frames and dead code. In fact, for any method with valid stack map frames, maxStack can be computed with a more efficient algorithm than the default one, which also works for dead code because frames are required even for dead code.

Improve the fix for issue #317823, which was not using a strict equivalent of the Analyzer algorithm (the labeling of the subroutines was depending on their order of appearance in the bytecode sequence).

See merge request !172

Add an experimental suffix to the new features (also mark them deprecated and show a big warning in the Javadoc). Revert to ASM6 for the default api of the visitors, and use ASM7_EXPERIMENTAL only in tests (only exception: Trace*Visitor classes, which are final). This pattern could allow us to develop any new feature directly in 'master'.

Improve the quality of the code related to ConstantDynamic.

See merge request asm/asm!169

Add an experimental suffix to the new features (also mark them deprecated and show a big warning in the Javadoc). Revert to ASM6 for the default api of the visitors, and use ASM7_EXPERIMENTAL only in tests (only exception: Trace*Visitor classes, which are final). This pattern could allow us to develop any new feature directly in 'master'.

Add a task to generate a sigtest file for the current version.

See merge request asm/asm!167

Fix Gradle build error introduced with last commit (looks like a Gradle or Jacoco Gradle plugin bug).

Resolve "ACC_SYNTHETIC attribute is still lost if constant pool is retained"

Closes #317825

See merge request asm/asm!170

Add unit tests cases for ConstantDynamic and fix bugs found with them.

See merge request asm/asm!165

Improve the quality of the code related to nest mates.

See merge request asm/asm!168

Resolve "ACC_DEPRECATED flag (or corresponding attribute) is lost if the constant pool is copied"

Closes #317822 and #317824
