build.log

build log and emerge --info
Comment 2 Volkmar W. Pogatzki 2022-05-25 08:31:27 UTC 
Since the build script [1] does not even mention ant it should be possible to build this package using java-pkg-simple.eclass instead of java-ant-2.eclass.

[1]https://github.com/i2p/i2p.i2p/blob/i2p-1.7.0/build.gradle
Comment 3 Volkmar W. Pogatzki 2022-07-09 08:24:02 UTC 
All this trouble is caused by unnecessarily inheriting java-ant-2.eclass. However, re-writing version ~1.7.0 with java-pkg-simple.eclass seems not worth the effort.

Solution:
Ensure to build ant-core and ~i2p-1.7.0 using the same GENTOO_VM.
Comment 4 tharvik 2023-01-29 18:55:08 UTC 
it seems that it was fixed by re-lowering ant-core minimum JDK

see related https://bugs.gentoo.org/831290

Sorry, but it is still reproducible. 
1. Have ant-core compiled with system java-vm = openjdk-17
2. Change system java-vm to openjdk-8
3. emerge net-vpn/i2p-1.7.0

net-vpn/i2p-2.1.0-r2 build.log with icedtea-bin-8 as system java-vm
Comment 7 Giuseppe Foti 2023-05-25 17:52:28 UTC 
The same error appears while compiling net-vpn/i2p-2.1.0-r2 and java-vm is icedtea-bin-8 (build.log attached).

net-vpn/i2p-2.1.0-r2 builds successfully setting system java-vm to openjdk-bin-17
