By using the subterm criterion [SUBTERM_CRITERION] together with the size-change analysis [AAECC05] we have proven that there are no infinite chains for this DP problem.

From the DPs we obtained the following set of size-change graphs:

• 970_0_HEIGHT_FIELDACCESS(java.lang.Object(BTreeR(java.lang.Object(x0[0]), x1[0]))) → 970_0_HEIGHT_FIELDACCESS(java.lang.Object(x0[0]))
