The regrtest for Jython 2.7.2a+ will show the following failures under OpenJDK 1.7.0_75-b13 on Windows.

Tests are test_bytes test_codecencodings_tw test_lib2to3 test_shadowstr_jy test_str test_string test_sys test_unicode test_userstring

Shows as an OutOfMemoryError:

Found during this work https://github.com/jythontools/jython/pull/132 which also shows passing on Oracle 1.7.0_80-b15 and other versions.

Given the current out of life state of Java 7, we may not necessarily choose to fix this, but I thought it worth documenting here regardless.
